Decent Practice Amp

Discussion in 'Amps and Cabs [BG]' started by Usul, Jun 3, 2001.


  1. Who makes a well built,good sounding,solid little practice amp?
    Need something small to take when I go out of town or to a freind`s house.I had an Ibanez 10 watt but it really sucked in the sound dept.I hear the Danolectro nifty 70 is good,and the pignose too...


    Thanks

    Peavey Microbass does the trick. Very portable, very inexpensive and... well, it doesn't sound half bad, considering its size.
     
  3. A Hartke b30 is really nice, too.

    Avoid Trace Elliot combos.

    An old Gibson "Thor" showed-up at Elderly recently.

    All-tube / 2x10" / 50 (?) Watt combo / EL34's / $300.

    I agree, the Peavey microbass is the best practice amp, IMHO. I'm thinking about picking one up.
    I've read in some reviews that they can even handle playing small shows.
     
  6. Don't overlook the Peavey Minx 110. It is a very nice practice amp, and does ok with the low B. They are fairly plentiful on eBay.

    I'm going to hotrod my Minx 110 by putting the amp guts into a slightly bigger cabinet with a different 10" and a 6" mid-bass. It will only be a few inches taller than stock, and will remain portable.

    The Microbass is a really nice amp. I hear that some people are taking them to gigs, then miking them up. By doing that, you can play small gigs with it. Nice bottom end for an amp its size.
    Worth a look IMHO.
     
  8. Peavey Microbass or Fender Frontman 15 or 25.

    G-K has a 400RB 112 combo that would do the trick very nicely. It has the 400RB head in it. Check American Musical Supply (americanmusical.com)--I think they have great prices on those. It would be great for practice and even rehearsal in a pinch.

    Can you say "overkill"? :D And $680 for a practice amp...? Well, if we're going that route, I might as well suggest the EBS Drome 1x12" combo... best "practice amp" the world has ever seen! ;)

    I agree with Oysterman. The GK head would be an overkill. If you're gonna get something like that, you might as well spend a few hundred more and get a head and cab.

    I suggest the Peavey Microbass, or the Peavey Minx 110.

    I'd go with the Peavey Minx 110. I picked mine up at a pawn shop for about $50 and it has been WELL worth it. They sell for about $225 new, but you could get one on eBay for around $80. This is a really nice practice amp with plenty of volume and sound for the $$$!!!

    my microbass crackles, pops, etc. But it may be because my cat pissed on the cone, but i think it crackled before that. It is an early 90s one 92 or 93, and i got it brand new. The peaveys are a lot better than they were then. I would go for a 15" combo, but that is just imo.

    Portrait, it's probably either rumbled some soldering loose... Either that or you blew the speaker, both are common problems in practice amps. They're usually too small to handle the bass they get pushed through 'em.

    Check out the Yorkville BassMaster 50, light weight i.e. less than 30lbs, not terribly expensive and great sound.

    Hey!! That's what I did today... and posted a question about a app I downloaded from your website.

    Instead of 1x6.5 I made a new box, large enough to contain 2x8 speakers.

    I built it so that the amp electronics would fit in, just as it does with the smaller cab... so now I can choose either.

    But, I assume that in such a small box I should port it... and wanted to use your program to figure out what size of port to use.

    Could you define the terms it requests when you "add a driver"? I don't know what info to try to find out from the place I bought the 8s.

    Thanks!! I guess I better delete the other post since I wrote all this...

    The above site is pretty good at explaining port calculations. You'll get kind of close, but the only accurate method is using a digital volt meter. You do it by getting a 100 ohm power resistor from Radio Shack for under a buck, and putting the 100 ohm resistor in series with your speaker line.

    The volt meter is attached across the speaker connectors, so you are reading the voltage across the speaker itself. The 100 ohm resistor keeps the circuit at a constant voltage, so you are reading the changes at the speaker that result when it hits resonance. The lowest voltage is the box tuning frequency. It will coincide with the least apparent cone movement (unless you have air leaks).

    When you add a 2nd driver (speaker) to a cabinet, it doubles the amount of cabinet volume required. If you use the Perfect Box program from my site, it compensates for this by asking you. Perfect Box also does box sizing and port calculations.

    Porting a small box to a low frequency will require a large diameter port to reduce air velocity, and a long duct length to tune it correctly. Don't be suprised if you see long lengths. Use the web site calculator above to determine the minimum diamter port size.

    Thanks a bunch! I noticed that this website gives you the minimum diameter, but also gives you a minimum area. If the min diameter was 4" and the min area was 12.56", could I ignore the min diameter and make multiple smaller ports that added up the the desired area?

    I noticed on multiple speaker boxes that often the speakers are rated at 45 hz or so but the cab is tuned lower. How can you determine how much lower you could tune a box by adding mutiple speakers?
