Projection-Plus Tambourines

Hand-crafted since 1979!

Grover Pro Percussion combines modern technology with "old world" craftsmanship to produce the finest concert tambourines available. Our Projection-Plus Tambourine provides you with the dynamic response, articulation, and tonal colors needed to sound your absolute best. Each tambourine features a premium, "natural skin" head which is glued and tacked to a solid, steam-bent, hardwood shell.

Our unique, "hand-hammered" jingles are made from three special alloys: German Silver, Beryllium Cooper and Phosphor Bronze. These resonant alloys have been tested and developed by Grover Pro Percussion to produce only the richest, most sonorous sound. Unlike other tambourines, our jingles are mounted in a staggered, "double row" arrangement that makes smooth rolls effortless.

Innovative, dual-sized jingle slots (two different size jingle slots cut into each shell) produce "out-of-phase" jingle motion, facilitating smooth, consistent rolls. Finally, our 100% captive jingle pins guarantee that the jingles will never loosen from the shell. All Models In Stock!

Maple or CST Shells
Our Maple Series features 10-ply shells, constructed from cross-grained New England Maple. We hand-pick only the finest Maple shells, offering a traditional warm tone and superior resonance. Our CST Series utilizes state-of-the-art composite shell technology. The result is a virtually indestructible, thin drum shell with a distinctive bright tone and ultra-sensitive response.

Precision DNC Bearing Edges
Utilizing automated DNC technology, Grover machines all bearing edges and snare beds to extremely close tolerances, resulting in optimal drumhead vibration and drum shell response. DNC technology measures the density and depth of each drum shell and machines a custom bearing edge and snare bed accordingly. This custom process results in precise drumhead seating, easy tuning and a consistent attack and decay across a wide dynamic range. A final "hand-sanding" process assures a silky smooth finish.

The Finish
Our CST drums feature a traditional black-gloss finish while our Maple drums feature and elegant, 10 coat, hand rubbed, lacquer finish. Available in Rich Walnut, Natural Maple, Deep Mahogany or Charcoal Ebony.

The Hardware
The close tolerance of DNC technology assures perfect placement of all mounting holes. All hardware fits tightly with no air leakage. Our nodal venting system places a unique Air Dispersion Vent (ADV) at the shell's minimal vibration point. This allows for a faster transient attack while the multiple ports precisely focus and contain air dispersion to maximize the drum's decay.

Our nickel-plated tube lugs reduce mass loading on the shell circumference, enhancing the shell resonance and sensitivity. Minimal "shell-to-lug" contact allows the drum to vibrate freely while our 2.3 mm super hoops provide dependable, consistent tensioning without choking or altering the quality of the drum's sound.

Piston Strainer
One of the greatest features of the Projection-Plus snare drum is the Piston Strainer and Snare Outrigger System. A 5-point adjustment system lets you tension the snares both laterally and vertically. We adjust each drum to factory specs, which insures maximum articulation and the ultimate in snare sensitivity. The Piston Strainer is the quietest, smoothest, strainer ever made! Our GIS Indexing System allows you to note your strainer settings for consistency, or in case you need to change settings during a performance.

Concert Bass Drum

Our Model BD-1 bass drum features an 18 x 36", 10-ply, New England maple shell, solid maple counterhoops and a 10 coat "crystal clear" lacquer finish. The BD-1 utilizes 14 tuning lugs on each side, which is more than any other bass drum in its class. This enables more precise, even tuning of low fundamental sonorities. We custom cut our bearing edges to maximize low frequency response across the large dynamic range. The BD-1 can be supplied with either key rods or T rods and comes standard with Remo Renaissance heads.

SB-104 Bass Drum Stand
The new SB-104 is the perfect suspended bass drum stand for our BD-1 concert bass drum. The SB-104 features 360 degree rotation, a suspension system that requires No drilling into the bass drum shell, locking wheels for easy transportation, and a shock cord suspension system that maximizes low frequencies. It is also available separately and will support most conventional concert bass drums.

Super-Overtone™ Triangles

Our Super-Overtone Triangles are the culmination of years of extensive research and experimentation. Each triangle is formed from a specially treated carbon steel alloy. The resulting wide spectrum of overtones, coupled with an extraordinary large dynamic range, provide this triangle with its characteristic sound. Unlike most triangles, the overtone resonance of this instrument will remain consistent throughout the expanded dynamic range. Our Kanigen plating is durable and allows the highest harmonics to respond, unlike traditional chrome plating.

TR-6 Our 6 inch triangle features a higher fundamental tone while retaining predominant overtones. This model produces a lighter sound than its larger companion.

TR-9 Our 9 inch triangle has a large internal working area which facilitates execution of the most difficult passages. the TR-9 has a full, rich sound.

HSH™ High Super Overtone Triangles

The result of 2 years R&D, each Grover HSH™ triangle is individually hand made and uniquely hammered. So special are these triangles that we individually number each one with a unique serial number. By combining the use of special bronze and nickel alloys, we are able to further enhance the very highest overtone frequencies. We effectively dampen the fundamentals through a special hammering process, thereby, filtering the lower partials and fundamental. What shines through is a resonant array of high frequency overtones. Available in both 6" and 8" sizes. Made from a very special alloy, each triangle is hammered over the length of all sides. Due to the strenuous hammering process, only limited quantities of these fine triangles are crafted. Contact us directly if you have trouble finding one.

While these are not the only hammered triangles available, you'll be very happy to know that ours cost less than 1/3 the price of imported hammered triangles. For the price of one of theirs, you can purchase our triangle, tambourine, woodblock, and still have money left over!

Model TR-HSH-6 (6" triangle)
It features a higher fundamental tone while retaining predominant overtones. This model produces a tonally higher sound than its larger companion. Model TR-HSH-8 (8" triangle)
Its large internal working area facilitates execution of the most difficult passages.

Alloy 303 Triangle Beaters

After years of research and testing, we've developed a "traditional style" triangle beater that produces a rich, full sonority with minimal contact sound. Alloy 303 triangle beaters are extra long (8.9") and are available in six sizes and weights. Each comes with a "color coded" plastic-coated handle for positive gripping and quick identification.

TB-S Standard Set (1 of each model)
TB-D Deluxe Set (w of models 1, 2, 3, and 4 and 1 of models 5 and 6, with a cordura case)

Tubular Triangle Beaters

These "contemporary style" beaters feature a tubular beater face (Alloy 303), isolated from a core shaft using a special rubber compound. Each beater comes with a comfortable, black latex handle (identical in diameter and coupled to the beater face). The increased weight of the beater face will produce the greatest array of spectral overtones from any triangle.

TB-TS Standard Set (1 of each model)
TB-TD Deluxe Set (2 of models 10 and 11 and 1 of models 12 and 14 with a cordura case)

Triangle Accessories

Dual Triangle Mount
The Dual Triangle Mount allows you to mount your triangles from any standard cymbal stand. The versatile side-arm extension enables you to mount your triangle (from 4" to 10") in a vertical or horizontal configuration. The vertical configuration allows you to mount two triangles at once! Our exclusive "nodal" suspension system allows maximum resonance from your triangles. The DTM is perfect for orchestras, drum set players or multi-percussion set-ups.
(Model DTM)

Pro Triangle Clip
Our Pro Triangle Clip is manufactured from New England hardwood for its strength and light weight. The easy action spring allows the player to open the clip with one hand (unlike bulky steel clips), so the triangle may be removed and clipped to a stand using only the holding hand. Our exclusive "nodal" suspension system allows maximum resonance from your triangle. In addition, we have secured a second line to act as a "safety" line.
(Model PTC)

Bass Drum Mallets

Our brand new Artist's Choice Bamboo Bass Drum Mallets feature the same high quality, hand-lathed, bamboo handles as our Bamboo Timpani Mallets. Unlike other bass drum handles, our lighter bamboo shafts provide greater leverage for the player, resulting in a more focused sonority and enhanced "bottom end". Meticulously sewn German felts, combined with the highest quality bamboo shafts, are sure to make this new bass drum mallet the professional's choice!

Our traditional Maple Bass Drum Mallets feature an elliptical "weighted" head, sewn with the finest German felt. An extra long New England Maple shaft provides a solid feel with exceptional balance. These mallets are durable and produce a round, focused bass drum sonority.
