Hi, I've been contemplating an amp build for the past year of so and was originally looking at a 50W 1987 with a switchable circuit to a 2204 and PPIMV. However lately as I am getting more serious about ordering a kit, I'm now leaning towards an 18W Plexi voiced amp head (I also plan to purchase a speaker cab with 2 x G12H30's). Having never played an 18W I have lots of questions...... I play mostly classic to hard rock (Guns N Roses, Zeppelin, ACDC, Hendrix) and some 80's and 90's metal. I currently just run a Vox AC10 on clean and use pedals for my desired sound, I don't gig at the moment, mostly play at home and jam with people, however since I've been getting back into playing, in the future some gigging could be on the cards and need something more powerful than the AC10. I'm thinking an 18W at 8-9 will sound sweeter than a 50w at 1-2? Will an 18W be enough for small gigs? What sort of headroom do you get with an 18W to be able to run clean sound at higher volume? Will an 18W be a good pedal platform for playing metal? What are some good kits? I've checked out the Valvestorm (they don't have cabs though by the looks), GDS Amplification (also don't have cabs by the looks), Mojotone and Trinity Amps), they all look pretty good. I'm in Australia so one of these kits + shipping + AUD conversion to USD is more expensive than buying an off the shelf Marshall 20W JCM800 Lead Series Studio Classic Head locally! Would I be better off just getting the 20W? I have an electrical trade and I have build over a dozen effects pedals, some fairly complex, so I'm pretty confident with my soldering and electronic abilities. Any help greatly appreciated, thanks.
