Hello all. I am looking to build my first amp from scratch (a 5F1 champ) and am trying to figure out how loud I can make it. I have looked all over the internet and have found lots of numbers, but nothing that I can call definitive, so I will just ask directly: If I pair this 5 watt circuit with a super efficient 12" Tone Tubby 40/40 (or any other similar speaker) that is rated at 101 dB per 1 watt, will that be loud enough to hold with a band? Any insight would be much appreciated.

True. Like Hendrix, White Stripes, Gary Clark Jr. kind of stuff. Not trying to play metal or anything like that.

it may
I have found very few low power amps that can work in my band situations. My 20 watt 1980Jr is the smallest I can get away with
2002 PRS CE22
2013 G&L ASAT Deluxe
2009 Epiphone G-400 (SH-4)
Marshall JCM2000 DSL100
Krank 1980 Jr 20watt
Krank Rev 4x12 (eminence V12)
GFS Greenie/Digitech Bad Monkey
Morley Bad Horsie 2
MXR Smart Gate

Should be okay for the most part. Don't expect cleans though.

Hm. Seems like volume could be there, but now I am kind of rethinking this. Maybe it would be better to build something a little more powerful just for the sake of a little extra headroom.

Clue: amplifiers amplify so don't turn it on if you need quiet.

Might just go for an 18w build then, plenty of kits around. Combine it with an overdrive and/or fuzz pedal and you should be good to go for the music you play.

Roughly 108db which is just shy of the 110db probably needed to run with a drummer on it's own. Add an SM 57 in front of the grill and you will be as loud as your PA can get. 130db??

15-20w with a quality speaker is tried and true for a lot of pub gigs. Blues Jr, Orange TT, Deluxe Reverb have been getting it done for decades.

Thanks guys. I think I will go for an 18 watt or something similar and not gamble on this 5 watt idea.

If you're going for 18W, you may as well go for 30-50W.

A 5 watt tube amp can get you kicked out of your apartment.

Might as well go for an AC30 clone then.

i built a 18w and a 5f1. (and a JTM45)

a 5f1 is LOUD, i have used it over a drummer (unmic'd), dimed, and i was fine. BUT the problem is that the sound needs to get disbursed, a 1x10" or 1x12" cab wont spread the volume around enough, so what i would do is throw a cab on each side so it would be heard better. it was fine. mic'd there is no issue though.

the 18w is too loud in most cases if you are really wanting to 'open it up' i love it, but you are going to go deaf if you dime it. way too loud for poweramp distortion in 99% of applications.

to me the 5f1 is more functional IF you DON'T need cleans, and like the tone.

i also built a JTM45, but it hasn't been running for a long time. i just haven't gotten around to it yet. that sucker is really loud. i love it with a nice pair of KT66's.
