I heard a lot of issues regarding the active EQ's of the Sansamp GT2 or Bass Driver DI as it it too hifi sounding. Well, for me it doesn't really bothers me at all because I always like these pedals. What I have here is a 3 band active EQ taken from the other Sansamp - the Tri-AC. I didn't mean to replace the existing stock EQ of the original circuit but rather using both one at a time will be a good idea. By using a DPDT or 3PDT toggle switch, meaning only one EQ circuit will be used while bypassing the other, not bad huh?. Please watch out for the connections. The pad labeled "V/2" refers to Vref(4.5V) and should be connected in the main GT-2 board where Vref is located. You should know it's location, say, if Tonepad's board is used(ORANGE colored pcb tracks). There's plenty of room to drill on that board. IC is a matter of taste so try whatever suits you best and always use a socket.

hi..just wanna ask how am i gonna wire the 3 band eq to sansamp gt2..where does the in/out go...im realy confused on how am i gonna incorporate it..
ReplyDeletetnx and looking forward
Is that a DIY Sansamp GT2 of yours too?..
ReplyDeleteJust like the anonymous said, Could you make a tutorial on how to wire the in and out of this eq to the tonepad gt2?
ReplyDelete:D
Awesome job man.
@rapidriot..yup its tonepads gt2 clone..
ReplyDeleteTake a look at IC4a(at tonepad's schematic and silkscreen board), cut a trace right AFTER the 0.1uF capacitor, located just below the HIGH pads. DO NOT cut the junction of the 10K resistor and 0.01uF cap. Now, let's go to IC4b and take a look at the board, there's a 1K resistor(above the lone NPN transistor connected to it's BASE), correct?. Cut the trace in between(that vertical trace just under the 1K resistor).
ReplyDeleteNow you can connect the IN of the new three-band EQ right after the other terminal(the recently cutted trace) of the 0.1uF cap while the OUT goes to the (upper)terminal of the 1K resistor(not the trace that connects the 10K resistor and 0.01uF cap to the out put of IC4b). That's it!
Will this dude work well with Bass driver DI? Or do I have to change some of the parts to make it more bass-specific?
ReplyDeleteYes, it should work as is..
ReplyDeleteIn bypasing the original tone control of the GT-2 (from the schematic), are the .1 cap and the 1k resistor INCLUDED or EXCLUDED in the mod?
ReplyDeleteSalamat bro.

Bro, Can this circuit be grafted to the sansamp Classic clone over at FSB? I'm planning to change the single Treble pot with this circuit. Salamat.

What is the V/2? and can you send me a schematic and a picture of an actual finished circuit board? mrridgely@aol.com
ReplyDeleteCan you send me the schematic and a finished picture of the project (BassDriver or GT2 its the same)? Thank you! gianinettoluciano@gmail.com
ReplyDeleteYou can send me the schematic and layout drawings of the same project GT2 with a 3-band equalizer to farizakhmat@gmail.com email address?
ReplyDeleteThank you
Hello from Peru ... i just did this eq and the volume is very low and the treble control doesnt hav much treble at all at max. position. Any ideas?
ReplyDeleteCan u send me complete project please,I don't no what is the V2,
ReplyDeleteMy e
Hey man,
ReplyDeleteI would like to build this eq on its own. Is it somehow possible?
