For personal physical reasons I own & use a number of small Bass Amps incl PJ Nano Amp. Whilst I follow the technical argument for multiple small speakers I still prefer a bigger speaker. This Amp with a 7” speaker and tweeter is able to produce a warm soft Bass output and more treble attack output, Bass used to evaluate was a Spector Bantam 4. Given the size, weight and price tag I am very pleased with this Amp, in fact I prefer it over the Big 4 - personal choice. Also l, it fits nicely into a Gorilla 12” LP Hardshell case for safe & easy transport 😉
