This is a DIY handbuilt point-to-point replica of a 1965-era Marshall JTM 45 guitar amp. Affectionately referred to by vintage enthusiasts as a “Plexi” (the gold plexiglass faceplates were later replaced by brushed metal ones), these early Marshalls are known for their rich, shimmering harmonics, and dynamic interaction with the player’s picking style. The tube rectifier ads an extra dimensional quality to the notes, allowing expressive detail in every note. Since there is no master volume on these amps,if you want distortion, you just turn it up louder. A Weber MiniMass attenuator is used to bring the volume down to practical levels while still letting the 50 watts of KT66 power tubes saturate the tone. There are a few custom modifications made, including a Mercury Magnetics ToneClone output transformer, NOS vintage Mullard/Phillips mustard capacitors, and NOS Allen & Bradley carbon comp resistors. Matched with a THD 2×12 cabinet with custom-made Weber pre-Rola spec Greenback clones.
