Garash G.TEN - ten band graphic equalizer in 500 series format

G.TEN is a 500 series format ten-band graphic equalizer. It’s a great sounding and easy to set EQ with all the important musical frequency points.
It’s great for shaping drums, guitars or any other sources where you need a great sound and fast setup.
The EQ is based on an IC gyrator filter which mimics an inductor. The G.TEN has proportional-Q (wider Q on low boost/cut and narrower Q on high boost/cut). This style of EQ became popular in the mid 70s when the famous console module was invented by Al Davis. G.TEN is input balanced and output balanced. Output buffer is implemented on 2520 discreet operation amplifier (DOA) that boost output transformer. G.TEN has true relay bypass with a led status indicator.

- standard 500 series VPR module size
- 10-band graphic eq
- proportional-Q band curves
- 12dB of boost/cut (with 3dB gain change mark lines)
- custom ordered center detent slide potentiometers
- 2520 style DOA output buffer
- our own designed and manufactured output transformer
- excellent for tracking We produce the G.TEN in small batches, each batch trying to improve its parameters. The fourth version is currently the newest and most advanced version. G.TEN V4 changes include the connection of the output transformer, several resistors have been replaced with more common values and their location on the board. There are no other circuitry changes in V4 compering to previous one V3.
G.TEN V4 is available as an assembled unit or as a diy kit here: Latest assembly guide:
