BOSS SYB-3 Bass Synthesizer No dry signal in Mono out

I have a Boss SYB-3 Bass Synth pedal that only outputs the effected signal when using the OUT A (MONO) jack. If I plug another jack to the OUT B it works as supposed to (OUT A: FX, OUT B:DRY). I´ve traced the dry signal and it stops right at Q7´s pin2, no more dry signal at Q7´s pin1. I don´t know i...

Re: Tech21 - Sansamp Bass Driver [schematic]

First of all sorry about the necrothread... does anyone figured out how the Ground lift and line/inst switches work? I´ve built it and it works great, but i´ll like to have those 3 switches options. Had the chance to compare it to my bass player´s Original Tech 21 Bass Driver, going direct to a mixi...

Re: Fortin - Grind Pedal

I have both grind and 33. They are on loan because my amps are really too tight to boost. I thought the 33 said OPA2604, but maybe it said "OPA604" (single version of OPA2604). I'll track them down this weekend and confirm. Did you got them back? Some pictures of their circuit boards will be awesom...

Re: Fortin - Grind Pedal

Nice pic, looks like less SMD in the 33 than the Grind. I think the 33 is all thru hole components and uses the same wima MKT caps, maybe to preserve some "mojo" from the original (and maybe fredrik does not like smd). Grind is almost completely SMD Edit- never mind I did write it down, based on th...

Re: Fortin - Grind Pedal

I believe you guys are right about the grind/33 being a TC Electronic integrated pre clone, makes sense :thumbsup nice layout & scematic here.. http://www.rullywow.com/wp-content/uploads/2015/05/ChuggaPre-v1.0.pdf Yes, I hope there was more pics of the insides of the Grind/33 to identify the cap va...

Re: Fortin - Grind Pedal

My original TC electronic integrated preamp has a UA741 in it. There's another schematic floating around that specs a 741. When I built a clone of it, I couldn't hear a difference between a 741 and a TL071, probably as the integrated preamp shouldn't be clipping the op amp, and it's not like guitar...

Re: Fortin - Grind Pedal

Looks like this pedal has three circuit sections. LT607 voltage booster - appears straight from the datasheet TC integrated pre - see the top left of the pcb there are the two transistors and diodes set up as a constant current source, part for part copy. Bass knob fixed I'm not sure about the lowe...

Re: Tech 21 - Bass Driver DI [schematic]

Sorry, i've posted the wrong picture :oops: This is the right one: First of all sorry about the necrothread... Is this ground lift verified? What are the benefits of it against just putting a plain SPDT switch to connect/disconnect ground? Also does anyone figured out how the line/inst switches wor...
