Looks nice. That one is kinda pricey, but otherwise exactly what you want. Id go for a cheaper one and take it to a tech for a tune up, testing and possible modifications. Most old amps will need new filter caps and the selenium rectifier replaced (unless its tube rectified) Dont let the them mess with the tone section.

That IS an impressive amp!

With 8 power tubes pushing 200 Watts you are sure to be heard over the drummer!

yeah, on second look, the price isnt so bad. Didnt realize it was 200w. That thing is a monster. Good chance its in decent working condition with good tubes. the wood box is nice too. bogen wasnt known for beauty. If you play with a band and need the power, this is probably a good choice. 8417's-gonna be tough to find replacements.

Guitar amps have a limited frequency range. I'm also a violinist and had trouble for years trying to get a good tone through a guitar amp. Eventually somebody recommended a JBL EON 15p G2 powered PA speaker (there are newer, lighter models now). It's just like having a combo amp but sounds great!

I've been using a Behringer K-450FX keyboard Combo for years. It is not too expensive, has a 10" speaker and 40W output power, lots of inputs, a small mixer and equalizer and 99 digital effects...

I decided recently that it's still fine to play through it - when not at home.

When practicing or playing for myself (or testing certain theremin modifications) I found I should have something more "true" and I decided a week ago to have an active Yamaha MSP3 monitor speaker just for the theremin. That's the birthday gift I made to myself. I'm still waiting for the fitting mic stand adapter in order to be able to position it at the correct (ear) height behind myself, but already now I can tell that such a "precision" device is very helpful since it reveals much more details. And I found confirmed what coalport told here long time ago: backing tracks should not be played through the same speaker than the theremin since one risks to "cover" some elements of your playing.

So I'm currently switching to "small but nice" equipment, keeping the Behringer monster in the storage for the rare occasions when I can't refrain from playing in public.

In reading Merula's reply, Would a pair of good speakers do the trick? I would need to find a good effect box (I want to use the Theremin for my own music)... Gosh I feel like a dumba$$ asking all these juvenile questions...

Guitar amps have different component values in the tone section, more suited for guitar-type freq. but speakers do make a big difference. You could try it out with an old home stereo (full freq)speaker. Just match the impedance to your amp.

Okay... I have looked online, and I found this direct box... Is that what is needed if I keep my current Fender Amp?

Direct Box (

or just go the opposite and get a keyboard amp like this one?
Roland - CUBE 30W (

THank you in advance...

If I had your mailing address I would have something shipped to you at no cost!

Hum… Advice from guitarists?

You know why so many guitarists jokes are one liners?
So the rest of the band can understand them

Did you hear about the guitarist who was in tune?
Neither did I

What do you call a guitarist who breaks up with his girlfriend?
Homeless ..

I hope everyone takes this light hearted; I could have picked on the drummer.

Your Fender Accoustasonic is probably different than guitar amps intended for electric guitar. They are two different beasts. Your amp is voiced for accoustic gutiar and human voice. It probably has a wider-flatter eq response. It probably does not have the midrange hump of an electric guitars amp. It may be a pretty good amp for theremin and meet your needs of amplifying a singer and instrument well.

I think you should consider an attenuator before you persue other amps unless you have a large wad of cash. I may have reading comprehension issues, but it sounds like touchless may be offering you a free attenuator. If that is correct, you should go for it. If I am mistaken, then I have enough junk cluttering my workbench to slap one together and send it to you also.

A direct box may work for you (I admit I really dunno) but usually they have balanced XLR3 output and your amp instrument-input is 1/4 phono, so you would have to adapt. Other model direct boxes do have attenuators, but they are big cuts like -20 or -40 dB. That might be OK, I dunno, it seems like a LOT of attenuation. Usually DI boxes are used for connecting things-that-are-not-high-impedance microphones to a PA (which thinks everything is a high-impedance microphone).

Dont forget the volume pedal option either. Those should be available for $30 or so and be available at a guitar center locally or fairly cleaply online.

The definition of a gentleman: someone who knows how to play the banjo... but chooses not to.

EDIT: My blather above about high-impedance mics was backwards. I should have written low-impedance. DI boxes primarily serve the purpose of converting some hi-impedance instrument into lo-impedance the PA expects to see plugged in to it.
