It will be a tube amp for sure. The cost of tubes pushes the price up somewhat. My 30 watt Fender Hot Rod Deluxe costs over $120 just to replace a set of tubes.

A gigging 30 watts tube amp will cost around $650 and upwards a lot more depending on the brand. Solid state amps can be made for peanuts so sell much cheaper.

Players like the small tube amps because they can be driven much harder without getting too loud and can even be miked up onstage at a gig. I have played smaller gigs with a 5 watt Blackstar tube amp I have. A 5 watt tube amp can get pretty darned loud. Cuts through so much more than a 5 watt solid state amp can.

Guitarists love tubes. Tube amplification is a bygone technology kept alive by guitarists and audiophiles so they gladly pay a premium for that choice. Even though small tube amps can be used at gigs they are mainly bought to use in small apartments to avoid riling up the neighbors but still provide a hard driven tube sound.
