Solid state amps are cheaper, lighter and often louder with a quicker response time. They also require more maintenance, new tubes every so often and anti-biasing even less frequently. Tube or valve amps are noted for being warmer in tone and for distorting in a musical way when over-driven. Are tube bass amps better than solid state bass amps?Ĭhoosing the best amp comes down to three factors: From my personal experience playing small to medium rehearsal halls and upto 1,200 seat clubs - 400 watts has served me well. Having more watts is better than having too few, as I've noted above - the less effort that it takes a bass amp to reach the required volume the less the chance of blowing fuses or overheating your amp. 200 watts x 2 = 400 watts, so your ideal bass amp wattage will be 400 watts or more. So, if you have two guitarists in a band and each has a 100 watt amp, the total guitar amp wattage is 200 watts.

Multiply it by 2 to get your recommended bass amp wattage.

Take the total wattage of the guitar amp(s).

This is a great formula that I picked up while hanging out on the Bass Player Magazine Lowdown Lowdown forum: How loud does my bass amp need to be in a live band? A louder amp doesn't have to work as hard, which means less chance of overheating, blowing a fuse or damaging a speaker.

The style of music that you play loud, distorted guitars will murder your bass presence in the mix.Ī 100 - 150 watt bass amp is the bare minimum to use for rehearsals and small gigs 300 watts is better since it allows the amp to push out the same or louder volume with less effort or strain.

The size of club(s) that you play (the bigger the stage, the bigger the amp you need).

No signs of anything burnt or scorched at all (though again, I haven't flipped the board - will tomorrow).Īny thoughts? I'm more used to things with tubes in them.The Bass Guitar Amplifier FAQ is a work-in-progress. Previous owner told me that a "resistor" had blasted apart, and indeed there was a small chunk of something rattling around in the amp, but that something looked like the plastic/rubber/whatever coating from an NTC thermistor, though the two in this amp aren't "blasted apart", and the amp wouldn't function at all without them. Haven't pulled the board out yet so I haven't checked for cold solder joints. Didn't bother with preamp, since it's completely disconnected for my testing.

Here's the schematic for the power amp section: gallien-krueger-backline-600.pdf. Amp delivers plenty of power even while crackling, and fan turns on and off properly. Once the amp warms up enough to stop crackling (somewhere around 40☌ or ~100°f), noise at the output is around 1mv. I can see the noise when I probe Q14/18 base and emitter (perhaps it's coming from Q7A/Q7B, hmm.). Noise at the output is ~100mvP-P, and crackling can be up to 5vP-P, maybe higher (hard to catch on my analog scope). Power supply seems fine otherwise +-60v are nearly exact, +-35v and +-15v are within 10%, and no detectable noise on any of them. Scoping the power supply rails, there's a bit of ripple on the +-60v but nothing that matches the crackling at the output.

Hi all, I've got a Backline 600 that's giving me some nasty crackling and noise, which sometimes goes away after the amp warms up, even without the preamp board connected at all - meaning it's the power amp or power supply.
