I suggest you pick up a Neutrix set screw style 5 pin male DIN plug (check out Neutrix's website).  You can get this online just about anywhere - Mouser Electronics for example.   As for me, I need to put a disconnect between the footswitch and cable so I can drop an entire pedalboard on the floor and bring everything to it in a snake.  I solved the problem with a mating pair of 5 conductor XLR connectors that I put inline just outside of the foot switch.     If you're comfortable opening up the amp, I'd suggest making an extension cord and going 5 pin XLR all the way from amp to footswitch. 

I have just completed the same setup using a G-Sharp from TC Electronic and a C-Lator into an OTS50 - concern about the hiss coming from the G-Sharp, have you experienced same thing?

Thanks

I just ordered a 50W Overtone Special.  This is my first experience with these amps.  I'm coming from a rig where I put everything in front of a Super Reverb.   With the OTS, I'll use the onboard drive, wah, delay, a reverb unit of some kind, and a Boss TU-2 Tuner.    Sounds like I'll need an effects buffer so I'm looking for suggestions: 

1.  Should I get the C-lator? or Kleinulator?  At present I dont have any rack gear, everything's on the floor.
2.  I vision my rig to be:   Guitar (G&L ASAT, Strat, ES339) > Boss TU-2 tuner > amp input, then effects send > C-lator or Kleinulator > Budda Wah > TC Electronic Nova Delay pedal > Reverb Pedal> effects return.   Does this sound right? 

Cables:  10' cable from guitar to Boss Tuner on floor, 15' cable from boss tuner to amp input, short cable from amp to C-lator, 15' cable from effect send to wah/delay/reveb also on floor, and 15' cable from reverb back to effect return.   This is a lot of cables.. too many?

Appreciate the help, thanks!
