| Some amp manufacturors attach the reverb tank on the side of the amp in a verticle position. Is there a diffence in reverb tone & responce with the reverb tank in that position?

I don't know for sure, but my personal thought is vertical will affect the reverb's mechanical movement of the spring(s). I've never put two side by side and did an analysis with a scope to see if there is any real difference. I would also suspect that over time metal fatigue or sagging of the springs would be greater in the vertical position.
Generally, reverb units are mounted horizontally in the bottom of the amp cabinet as that is where there is space to mount it.

| Turn your amp sideways and listen. |

quote from road runner, (above)
"the reverb sounded like a thunder storm,poping and cracking,"
Thats why I went to a ProfexII. I played a gig one time where we were set up on a Hay Wagon. Once the drummer got to going, Mine and the Lead Guitar player's amp really got to raisin' cain. It was the spring units.
I tell this story to keep you from makeing a mistake in selling your ProfexII, then regretting it later. |

EB - I like your way of thinking! Sometimes we just make things too darn complicated. It reminds me of the story about all the money NASA spent in developing a pen that would write in zero gravity. The Russians solved the problem by using pencils.
I like the KISS principal.

Way to go Earnest!
I guess I was too close to the forest to see the trees! I'm glad I didn't ask how many steel players it takes to screw in a light bulb?

| It takes 7 steel players to change the light bulb. 1 changes it, the others stand around and say: Shoot, I can do that! |

Spring reverbs are adjusted at the factory for the expected mounting position. This is done to ensure the little torsion magnets that generate and pick up the motion are centered between the pole pieces under the influence of gravity. Other considerations aside, I think the manufacturers of the reverb would prefer to mount them vertically so gravity would not affect the location of the magnet in the pole piece space. But there are many other considerations that must affect the choice of location during amplifier design, such as power transformer hum pickup, for instance.
I found much useful information, including an explanation of their part numbering scheme in the booklet "Accutronics Reverb", which I obtained from the manufacturer,

Hello Dave:
Thanks for the information! It's always good to hear from another player from Massachusettes.

A few years ago I bought an Emmons amplifier and the reverb is really the only thing I can slightly complain about. The reverb in these amps are very touchy and the mounting location was wrong. They were mounted to close to the power transformer and hummed a lot. I placed the reverb as far away from the transformer as possible and replaced the input, output wires with George L cables. Cleaned the sound up considerably. With respect to mounting I believe horizontal is best because the gravitational pull is equal in all directions on the springs and is a lot less stressful on them when travelling.
Hope this helps. |
