Would this 5W Tube amp be a nice upgrade over my Fender 10W Frontman?

I play a lot of Santana and bluesy classic rock, very little to no metal.

There are better 5w tube amps. You should try the Fender Champ (change the speaker!) or the EVJ instead.

Princeton Reverb, Extra Reverb
P-Bass - Mustang Bass
