Guys, I let the lust for tone get the better of me. I came across a 4103 from the original owner. The amp is in remarkable shape. Its all original. I played one in a music studio with a borrowed 1958 Gibson Les Paul Junior about 5 or 6 years ago. I was selling them a Les Paul Standard and we started noodling. I played that rig and my jaw dropped. We were playing loud but the amp left an impression on me. Came across the 4103 yesterday on Reverb. The guy said he hasn’t used the amp in years and its never left his house. Its working flawlessly like new a d its all original down to the tubes. It has the 80s era G12T-75s in it. I actually like that speaker. To me its closer to a G12-65 than a G12T-75. I got it for $1150 which i thought is a good price. I will do a review when it arrives. Anyone play one of these. I don’t see the 4103 often.
