Vintage mid-60's Gibson GA-35 RVT Lancer- reverb, tremolo, footswitch. Classic tube amp, 7 tubes in all. I am not a fanatical amp guy,never had this one serviced.It is not getting any playing time. sounds great,reverb and tremolo work well.Sometimes the amp will make a little background noise, I think from lack of use.it's clean, but there are some white scuff marks on the vinyl casing.All of the dials work, and it is fairly heavy.Local pickup is welcome.I could not tell you the tube setup, but I imagine it is pretty classic and easy to find the schematic online.
