Knobs    

Click on photo for

KNOB, Original Marshall®, PUSH ON KNURLED
Standard original Marshall® control knob, push-on type.  Designed for the "knurled" type control shafts, such as the 16mm potentiometers shown above.   Used on the MG-series amps, except for the latest MG series with the large "MG" on the front panel.  Original Marshall® part. 

Note:  Marshall® recently switched to a new subcontractor to produce these knobs (late in 2016).   These new knobs are (1) more of an "orangey" shade of gold than the previous Marshall® knobs and (2) the gold caps have more of a matte finish than the previous caps which were shinier.  These new Marshall® knobs are unfortunately less likely to match the existing knobs on your amplifier.

KNOB SET, Original Marshall®, PUSH ON KNURLED, SET OF 6.   Standard original Marshall® control knob, push-on type, set of 6 knobs.   Used on the MG-series amps, except for the latest MG series with the large "MG" on the front panel.  Original Marshall® part.

KNOB SET, Revisit™ Quality Clone of Marshall® Knobs, Push-on Knurled, Set of 6. Excellent quality aftermarket Marshall® control knobs, push-on type, set of 10 knobs.   Designed for the "knurled" type control shafts.    Used on the MG-series amps, except for the latest MG series with the large "MG" on the front panel.   Due to copyright reasons, there are differences between the Revisit™ clone knbs and the original Marshall® knobs that we want you to be aware of.   The clone knobs' gold tops are smoother than the originals, and the clone knobs are a very dark brown (almost black) while the original knobs are more of a dark chocolate brown.
Part #MKCPT-6

KNOB SET, Economy-priced Clone of Marshall® Knobs, Push-on Knurled, Set of 10.   Economy-priced aftermarket Marshall® control knobs, push-on knurled type, set of 10 knobs.   Fits most MG Series (except for the latest version), JCM900 series, and later JCM800 series with knurled split-shaft pots.  

Comments on appearance:  The gold cap color is close to the original Marshall color, but the finish on the cap has more shine than the original knobs.  Due to the additional reflection of light, the ridges in the knob tops might be a little more noticeable.  Color of the knob base is black.   The quality of the knob is quite good, and they are durable.  Economically priced, making a complete change-out of knobs very affordable.
