Aftermarket reverb tanks ?

[6L6C]

I have a Mark IV medium head.

What I would like to know are there any aftermarket reverb tanks out there? I’m looking for something a little different than what is currently in the Mark IV. The trick is I do not want to do any physical modifications, just swap tanks. Maybe a tank with more springs? Just something different really.

The Mark IV sounds fine, but I like say: the reverb of a Peavey Classic 30 allot better.

I normally play dry or use a processor in the loop (which covers all effects for me) but always found the reverb in the IV a bit weak. After jamming with friends the other day with my Classic 30 and a wah pedal I got it in my head I would like a better verb in the IV.

Boogie uses the 3 spring Accutronics 9AB2C1B Medium Delay Tank. You could use the 9AB3C1B Long Delay Tank but it would not change the tone of the reverb only make it last longer. To brighten it up like a Fender you would have to work on the circuit.
