1976 Marshall JMP 1987 MK II 50-Watt Head – Ex-Danelectro (Steve Ridinger) – CME / Brian Carstens Rebuild

Description:

A cool and unique piece of rock history and gear provenance: a 1976 Marshall JMP 1987 MK II 50-Watt Lead Head.

This head was previously owned by Steve Ridinger (Owner/President of Danelectro) and served as an in-house workhorse for Danelectro for many years, used extensively to voice and test guitar pedals.

Key Highlights & Provenance:

• Chicago Music Exchange Certification: Comes with official Chicago Music Exchange inspection documentation dated 12/4/18, made out directly to owner Stephen Ridinger.
• Rebuilt by Brian Carstens: Inspected and serviced by renowned boutique amp builder Brian Carstens (Carstens Amplification) during his tenure as CME's Lead Repair Manager.
• Fresh Maintenance: Recently retubed and biased. Runs quiet, hits hard, and produces classic, dynamic 1970s Marshall punch and crunch.

Condition & Specs:

• Year: 1976
• Model: JMP 1987 MK II 50-Watt
• Transformers: Non-original output transformer (replaced prior to/during CME rebuild, fully documented as part of its player-grade service history).
• Capacitors & Tubes: Clean chassis layout with Daly filter caps and power tubes freshly installed and biased.
• Cosmetics: Vintage cosmetic wear with authentic patina on the tolex and piping, consistent with a legitimate 1970s studio workhorse.

Whether you're looking for an incredible-sounding vintage JMP for the studio or a rare piece of pedal testing history, this head delivers in both tone and background.
