[Harp-L] Amp Head question

[ALAN FUNK <funkam@xxxxxxxxxxx>]

I have a buddy that builds rather impressive speaker cabinets. 
Mostly for guitar but also for bass and subs.
So thought maybe an amp head would be the right direction for upgrading my sound.
Has anyone had any experience with small tube heads such as Egnater Tweaker 15W Tube Guitar Amp Head?
Or maybe something else, their are a lot of options. 
Small tube head on speaker cab maybe is what I'm looking for.
Need some feedback please.
