    Hi all! I'm in the market for a channel strip or preamp that would mainly get use as a bass channel and vocal overdub channel. This being the budget gear forum, my first choice (and right in line with my budget) is the ART ProChannel...


    I've heard good things about it in general, but what about for bass and vocals specifically? Another prime contender, but very different, is the Groove Tubes Brick...not posting a link, I'm sure you all know wtf I'm talking about. Price is a little more, but still in line with what I want to spend on this upgrade.

    Anyone have thoughts about either or both of these for vocals and bass (honestly, bass is the main thing I'm after, but a better vocal sound never hurts), or any other pieces I should look into? Thanks! Andy

    API 312 module. Purchase 2. Purchase a bipolar 15 volt power supply. Purchase a couple of microphone connectors. Purchase a couple of potentiometers. You're in heaven. Don't look back.

    I know the API stuff is highly regarded, but I've never had the chance to use it myself. Remy, would that be in my range of $400 or less? I kind of doubt it, but I don't know for that model for sure. Keep in mind this is the budget forum, but if you could point me to where I can get a pair of API pres for $400 or so, I'd be thrilled!

    Actually the trick is to acquire an API 2520 op-amp. Then all you need is a Dean Jensen JE110k or JE115k or the equivalent Reichenbach microphone input transformer. You don't necessarily need the output transformer that API uses. If you want a balanced output try to find an old used UTC A-20 or Triad A-57J line level output transformer. That will give you plenty of color since they start to saturate at +15dbm into a 600 ohm load. You'll probably load it into 10,000 ohms or more. So you'll likely not saturate the transformer much. But that's half the fun.

    Unfortunately, I remember when the 2520's were only $45 each. Haven't priced one lately. I need a couple of replacements. You might want to try the John Hardy 2520 replacement? It's also a nice preamp.

    If you can find any use API 325 line level cards? All you would need is the input transformer to make a 312. That's pretty screwy math ain't it??

    Well,thanks for the idea Remy. I have no experience with electronics or soldering...so, this sounds like it might be over my head! Thanks anyway, though! Andy
