A friend sent this photo to me, no he did not buy but had an amp he wanted me to look at and advise.

I was hoping he had the Dumble and could send photos but NO!

Maybe if they throw in some free strings to sweeten the deal.

That amp was listed for sale on Reverb. I don't know if it sold or not.

"Dumble Concert Reverb, 1973 Santa Cruz era
Dumble-built Chassis in a '70's Super Reverb Cabinet...... this is not a modded Fender amp; it is a complete custom build."

Cheers,

In that case I'll grab the gut shots for posterity:

Minor detail but Dumble did not “build” that chassis. It is a Fender chassis with added faceplates.

I tried to dissect the guy shot photos earlier. I also believe Aaron has been working on tracing this one out too.

Note the treble and Bass boost toggles on the front. The treble one appears to toggle a cap in series somewhere.

It actually looks like it's wired in parallel with the ceramic coupling cap on V1B. Maybe parallels a cap?

So the front- and backplate might be of interest, too:

Can't quite make out the Vib ground mod.

I think he just wiped plates with MEK and wooled them, then used a paint pen to remark them back then, no?

It smells somewhat authentic but looks Mickey Mouse as all get out.

It's the way that era of stuff looks. Folk art.

All of those slide switches suggest to me that it's not just a factory faceplate that's be repainted or flipped over. The chassis might have started out Fender, but the faceplate is custom.

I just saw this amp at the Guitar Show in San Rafael CA a couple of weeks ago. Seller would not let anyone get close to it.
