Finally, bias guitar amps offer a more natural sound than traditional amplifiers. This is because the biasing process reduces the amount of electrical interference that is produced by the amplifier. Second, bias guitar amps produce less noise than traditional amplifiers. This means that they require less power to operate, which can save you money on your electricity bill. First, bias guitar amps are more efficient than traditional amplifiers. The reason for this is that bias guitar amps offer a number of benefits over traditional amplifiers. However, they have only recently become popular with the general public. Bias guitar amps are not a new invention they have been used by guitarists for decades. In the case of a guitar amplifier, biasing can improve the amplifier’s ability to amplify the signal from a guitar. Biasing is the process of adding an electrical charge to a component in order to improve its conductivity. Still more clean volume than many tube amps in its size and weight.As its name might suggest, a bias guitar amp is an amplifier that uses biasing to improve its performance. I did buy a Hammerhead, but it gets gritty pretty quickly. Sounds good to me but don't see much of that.

Maybe not by a lot but hovering around the db range that a drummer would compete in.Ĭhoosing a modern 40-50w amp and adding a cathode bias option doesn't help the weight issue.Ĭhoosing a more primitive and light weight circuit like a 5e5 and adding a fixed bias option gets a small light amp with some extra clean headroom when called for. They can be built to virtually the same size and weight.Īdding a switchable fixed bias to the 28watter will bring it up to 35w or so, certainly punching above the 6v6 amp.

Hard to say if a 22w fixed bias 6v6 amp is more satisfying than a 28w cathode biased 6L6 amp at similar volumes. Not sure if the Fender hw reissues of those amps are the older cathode biased circuits or the newer fixed bias, but all are made by Victoria and other small builders and can probably be ordered either way.Ī list makes some sense to me because I'm tired of 'small amps', and find some nice middle ground in a smaller transformer, lower voltage, cathode bias dual 6L6 or el34 amp with a single 12, coming in at under 40lbs.Īctually, all those parts can be made a little louder and cleaner with fixed bias, while still being light weight, but the cathode bias gives more of the cranked amp feel at lower volume. Fender Prosonic has a switched cathode bias option.Ĭeriatone and other Marshall 18w TMB based amps.įender 5e5 Pro, maybe also 5e7 Bandmaster and 5f4 Super.
