1985 Marshall – Studio 15 Model 4001 – ID 6201

Small, unusual, and now quite legendary: The MarshallStudio 15 Model 4001 dates back to the mid-1980s and is one of the rarer Marshall models.
Instead of the big 50- or 100-watt powerhouses, this one features a compact 15-watt amp—a power amp with 2x 6V6 tubes, which was quite an unusual combination for Marshall back then.

This unit, with its light-colored front panel, was thoroughly inspected in our workshop; among other things, the power amp tubes were replaced and the speaker was repaired. The cosmetic condition is actually very good for its age; there is no damage to the Tolex or front fabric, just the usual light layer of dust and dirt.

Special Features:

• Headphone jack as a built-in attenuator. The amplifier features a built-in dummy load that mutes the internal speaker when headphones are plugged in. Guitarists still use this headphone jack as a handy trick today by plugging the speaker cable into it to significantly reduce the volume when playing at room volume.
• The first amp with a Celestion Vintage 30. Marshall first installed the now-legendary 12-inch speaker in this model. At the time, Celestion developed the speaker under the name “G12 Vintage” specifically for high power handling in compact cabinets.
