Marshall JMP 4150 Club and Country Compressor Bass Amp 100-Watt 4x10" Bass Combo. Professionally serviced by a vintage amp repair shop a month ago. It was tested, cleaned. The Amplifier is in perfect working condition. It is all original parts
Maybe 3' by 3'. Thats a guess
Hi David,
Thank you for contacting Mearto with your appraisal inquiry.
The Marshall JMP 4150 (often branded as the "Club and Country Bass" model) was one of Marshall’s rarer bass combos from the late 1970s and part of a small line of Marshall bass models from that period before Marshall largely exited dedicated bass amplification in favor of guitar amps and later hybrid/solid‑state bass series.
There just weren’t many bass combos from Marshall in that period, so surviving 4150 units show up less often than classic guitar JMPs.
Condition is considered crucial since these amps are 40+ years old and valves, caps, and speakers wear with age and use and often require frequent servicing.
I've found a few different "good condition" examples of this model retailing currently for between $1,500 and $3,000 but when these come to auction, they usually don't bring that much - usually between $700 and $1,000.
Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.

Hi David,
I would say this is in fair-to-good condition with wear commensurate to normal use and age (it doesn't look like it traveled) and is - condition wise - in line with other examples of comparable age.
I hope this answers your questions; let me know if you have more and have a great day,
Delia
Thank you for the appraisal of my Marshall amplifier. Only one question: What condition would you say mine is in? (Good, fair, excellent etc...) especially compared to others on the market.
Thank you
David
