The Purple Peaker is an equalizer for guitar or keyboards which introduces one or two peaks into the frequency response at specially selected frequencies.
They're back! The legendary Dan Armstrong Sound Modifiers are now available again and they're better than ever. These units are now 100% USA made and are hand-built to authentic 1975 Dan Armstrong specifications by Grafton Electronics.
Dan Armstrong Sound Modifiers are a range of simple, compact, and rugged accessories that can be used with any electrified instrument. They are designed to plug directly into the output of a guitar or bass guitar to give the player fingertip control of the sound, but they work just as well plugged into an electric keyboard or the output of any electronic accessory. Any musician, who wishes to use these units at the input of the amplifier, rather than at the instrument, need simply interchange two colour-coded wires inside the box.
All six units are built in a heavy duty aluminium casing, using only the finest quality components available. Overall dimensions are 59mm wide x 59m high x 70mm deep (including plug). The unit only protrudes 43mm from the face of the guitar. Weight is only 41/2 ozs, including battery.
Each unit has a specific effect or function, but several of them can easily be combined by plugging one into another to produce more complex effects. For recessed output jackplates (e.t.c Strat) adaptors are available to facilitate use.
All units come complete with a 9 volt battery already fitted, so all you need to do is plug in and play!
The Purple Peaker has a three position switch to select one, both, or neither of the two peaks. In the ",1", position, the Peaker introduces a 12 db peak centered at 4000 Hz which gives the instrument more ",presence", or ",bite",. In the ",2", position it produces the same presence peak plus a 7 db peak at 200 Hz to give the instrument more bottom or ",punch",. In the ",Off' position neither peak is produced, but the guitar's signal is still improved, since the Peaker's low impedance 200 ohm Output eliminates signal loss and hum pick-up, even with very long cables. The Purple Peaker makes weak-sounding instruments sound fuller, and full-sounding instruments sound super. It is also excellent for musicians who want to record themselves by plugging directly into a tape mach,ine without going through an amp. The Purple Peaker has an Input Impedance of 100 k Ohms, and an excellent Signal-to-Noise ratio of 90 db
