Thanks

A 4AB or 9AB should work fine. The 9 series sounds for lack of a better term. Bigger and deeper. I like the 9AB2 (medium decay), the 9AB3 can be a bit over the top.

The 4AB3 is also a good choice.

I have a Ruby 3AB2C1B that I bought a few years ago. The tone is great, rich and full, but the delay is measured in years, no milliseconds.

Thoughts on a really good sounding unit like the Ruby with a more reasonable delay?
I would look at the new accutronics 4 and 9 series. I think the 9 with a medium decay is the way to go personally. You could also try reducing the drive (dwell) to the tank. Especially if the tank is sounding splashy. Too much drive on the coils can create a lot of reflections giving the same effect.


I tried a few of the Mojotone tanks when the accutronics were unobtainium a while back. A total waste of money, pure crap.

My original reverb a loop was speing based and it is posted in the files section (back about 5 years).
Wow, looks really nice - great mix of old and new technology.

Thanks, only a couple exist, I have one and Henry Kaiser has the other. Someday when I get off of my butt I may offer them for sale.

The effects signal is parallal with the original signal so it doesn't change the original tone.

Thx, yes I bought this at the same time and I'm disappointed in it. No splash and I've tried lowering the dwell but it still doesn't sound right. Connecting the same amp to a 70's vintage accutronics sounds great but alas, I only have a this one good sounding vintage tank.

Thanks for posting this, it looks like a cool project. Sorry to be lazy, but how close is the effect loop to a Dumbleator?

Thanks

I played Henry's and it sounds great. Really nice product. :D

I'm curious where you sourced the digital 'verb from. Is that something you can share, Gary?
Wife: How many amps do you need?
Me: Just one more...

I have actually never played a Dumbleator so I am not sure. The topology has similarities however some of the component values are different I think.

With respect, 10thtx

Frank that could be worth looking into especially if I start going with PCB circuits instead of tag or turret board construction. :)

As Frank stated, I used an FX module for the DSP section. Worked out very very well, pretty easy to implement the unit in my standard Matchbox. I used the recovery amp for the loop as a parallel mixer.

The entire module is on a small PCB that has all of the components and is held in the box using the switch and controls.

No noise or tone change. The mixing is being done in the plates. So the two recovery amps operate independantly. I "steal" a little of the loop return signal into an extremely high input impedance buffer so there is virtually no loading of the original signal.

Henry K. tells me it is most transparent effects processor he has used with his Dumbles. He and I agree, the Plate settings are the best for guitar.

FWIW, the little interface board is not for the faint of heart. Double side PCB with components mounted on both sides. space was a consideration in my application.

Wondering if the DSP module could be incorporated
into to a standard Dlator circuit?

btw very nice unit Gary

You could easily mix the recovered effects signal back into the grid of the recovery amp, but you would have to take care for possible oscillations. I did something like this on my early SOD's for spring reverb. The recovery amp gave needed reverb gain.
