reverb tank mounting
« on: June 13, 2010, 10:46:32 pm »
I just started thinking about reverb tanks, is it advantagous to have the tank isolated from vibrations, as in a shockmounted sort of sense? I haven't messed around too much with amps with reverb, but the Traynor I just picked up had the tank mounted right to the plywood, but the hardware doesn't look original so i was wondering if this is how it would have been mounted originally. I have a musicman head that I've had for ages with the tank loose with two pieces of cardboard taped to the bottom, know it wasn't original but never had any reason to fix it. Anywho, thanks for any help with yet another newbie question. Cheers.

For a spring reverb, you do want it isolated in some fashion, as if it is solidly mounted to the cabinet, it WILL vibrate the springs and introduce some acoustic feedback into the amp. (or at least pick up every bump, tap, etc on the cabinet.)

Most mountings I've seen always seem to use a special bag for the reverb tank, at least commercially. on a DIY and Boutique note, I'll let the other chime in on how they do it, as I don't include reverb in my builds, so far.

I have gotten to where I mount my reverb tanks using a :

layer of foam double stick tape/wood screen molding/another layer of foam double stick tape. This also gets it up high enough that the springs won't bump the wood cabinet.

Seems to work pretty well and then I throw a piece of carpet of rubber shelf liner over/around it.

With respect, Tubenit

I've always taped a thick piece of cardboard over the open side of the tank, stuck it in a tolex bag (think it's tolex anyway), and held it down with long strips of velcro stapled to the bottom of the cab. (velcro wire mgmt. strips actually). 

However, a variation on tubenit's approach just occurred to me: some combination of a cardboard cover and double-sided foam tape.

Cheers,

Chip
