Has anyone built in a kleinulator in an Overtone? I would`t care for more boxes and cables than necessary so I think it could be a good idea. How about adding a footswich for bypassing the loop and maybe a boost?

I've got several threads open on this already. No need to stir the pot extra. These guys are sensitive about the effects loop.

I'd think there'd be room inside for an 8 pin op-amp and a cadre of resistors and capacitors. Hopefully there's space on the back panel for 3 knobs or so.

I'd rather see another tube than the op-amp. I think most here would.

I'm building a HRM with built-in dumblelator at this moment(not ceriatone), however your chassis has to be adapted to fit the thing.

No, straight HRM but other than Ceriatone's.
Bluesmaster will be my build after that, I already have the next chassis Grin

Which design do you follow? the 101HRM?

Respect for the big guy's work....we're at this part of the forum because of HAD's amps.

Yes 101HRM but with some presence circuit tweaks and HRM tonestack tweaks. It's not finished so I can''t say how it sounds...

Yeah erwin!!!!! Was the extra tube section an extremely tight fit?

If it all works out, kindly share the fruits of your labor with Nik.

BTW, erwin, I've an '91 Boogie Mark IV with a recording output, that somehow uses the speaker as "emulation", even though it shuts the speaker output OFF. Simple stuff to be sure, scale a line voltage from the speaker output.


HOWEVER, if an OTS had such a recording output, to be feed into a stereo effects processor, would there be a need for a Dumbleator at all?Huh?

 In other words, just send a dry signal to the processor, no loop in the equation. Might need an op-amp for a Record Out though.

BTW, would a "long" head version of the chassis (a la Fender and Boogie) give you enough volume inside  for the loop circuitry?

Maybe, I'm not familiar with the inside of the Mark IV; I'm very narrow minded, only dumble so far and a Fender. Grin

Here's a picture of the build a week ago. It's fitted in a old Peavey Classic VT chassis. So plenty of room.

Erwin, if you've ever seen Larry Carlton live, he places a microphone in front of his (100% dry) Dumble. The mic's output goes to stereo processor, then into the board. In essence, he did away with a need for an effects loop.

My idea of a RECORD output would be similar, but silent, and no microphone. Just a dry signal off the speaker terminals would be sent to a processor. That's how the Boogie Mark IV works, and it works very well.

That's a long head alright. I take it the right most socket is for a 12AX7 to buffer the effects?

BTW, which "Dumble" schematic are you using for this?
