It's funny - we all seem to be travelling on similar paths !

I have been working my pepper over in my mind lately and I'm going to install a toggle swith to bypass the tonestack as needed.

Okay - well that was a massive failure - all I did was completely cut signal - yes....aparrently the TS-a and TS-b need to be connected......duh......

I have three toggle switches at my disposal and I need to eliminate the tonestack at will:

On/Off - two contacts

On/On - three contacts

DPDT - six contacts....

needing guidance - I'm sure it's simple.

Thanks, Dan

DPDT - imagine you'll bypassing an effect.

Lift the mid pots ground connection. SPST is all you need.

Just to be clear - this is the tonestack I'm using:

So - a simple on/off between the gnd connection from the pepper board to the tonestack ?

Thanks everyone !!

Yep

Break the Blue wire or the Black wire, which ever...

Worked great - thanks again - oddly though - with the tone stack bypassed - turning the "treble" knob will slightly (ever so slightly) reduce the overall volume.

Just need to make sure the treble knob is at 10 whenever the tone stack is bypassed - no problem though - love it !

That's because the SPST doesn't truely bypass the tonestack. To truely bypass it you need the DPDT arrangement.

kurtlives · October 31, 2009, 06:06:13 PM

Ya forgot to mention that Dan.

Rick no offense but this method is way easier and does virtually the same thing. Never seen amp that "fully" bypasses the tonestack.

Really the treble pot shouldn't affect the volume too much, provided it seems the ideal input impedance. When boost engaged it should ever so slightly affect the highs. Dan are you using a Marshall TS, those rely on cathode followers before them generally.
