Ceriatone Forum

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.

No, straight HRM but other than Ceriatone's.

Which design do you follow? the 101HRM?

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.

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????

 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.

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

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

I know technically how it works; designing takes a long time: it's testing/adjusting over a long period.

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?

No the most right is the phase inverter, left of the phase inverter is the socket for the buffer.
Basically it's 101HRM with added d-lator and some tweaks.

Almost done only heater wires are left.
Any updates  on the builtin d-lator?

I noticed Bludotone has a built in tube effects loop. Larry Carlton now tours with Bludotone, leaving his Dumbles at home, btw.

almost done, only heater wires!

Er, ah, Erwin, you did leave room for transformers and choke? I don't see a cutout for the PT, which usually protrudes inside the cabinet. Perhaps they all get mounted on the surface?

Best of luck with it. It should be interesting to compare to your Ceriatone and various D amps.

Transformers are all on the bottom surface, the way it was mounted by Peavey. It's just a conversion so I left the trannys where they are.
