Home / Guitar Cabinets / Park G412 Guitar Cabinets (circa 1994-5)

By Brett McCarron

The Park G412 guitar speaker cabinet was styled after the 1960 series of 4x12 cabinets that Marshall has made for years. The G412 series was discontinued in 1995.

The G412 outer shell was made of plywood, with a removable back panel constructed of particleboard. The differences between the Park G412 and the Marshall 1960 series cabinets are explained below. Note that these are personal observations from the six cabinets I purchased new in December 1995.

The G412 cabinets match up with a stock Marshall head quite nicely, and they sound decent, too, thanks to the Celestion speakers inside.

G412 Information and Comparison to Marshall 1960 Series Cabinets

• Same external dimensions as Marshall 1960 A and B cabs
• 4 x 12" Celestion G12-L speakers (8 ohm, 35 watts)
• 8 ohm cabinet impedance
• 140 watts RMS power handling capacity
• JCM 800-style jack cup (see photo at right)
• Mono, single quarter-inch jack
• Removable casters (slightly coarser thread than JCM 900 casters)
• Particleboard cabinet back is not covered in vinyl, but is painted black
• "New style" Park logo in upper left corner of cabinet (snaps in place)
• No white piping around grille
• Other hardware (handles, corner protectors) virtually identical to JCM 800, 900 series
• I.D. plate on back same style as JCM 800 1960 series (see photo)
• Angled (top) cab does not have "no-slip" rubber areas on top surface to keep amp head from sliding off
• Bottom (G412B) cab does have caster cups like Marshall 1960B
• 1995 list price $649 US
• These cabinets were discontinued by Marshall in late 1995, according to Dave Broyles at Marshall retailer Music 6000 (Olympia, WA).

Important note: the G412 models are 8 ohm cabinets. Two G412 cabs in parallel equals 4 ohms. The SL-X heads operate at 8 or 16 ohms. You cannot use a pair of G412 cabs with an SL-X unless you either have your head rewired to accept a 4 ohm load, or you rewire the G412 cabs to a higher impedance (i.e., all speakers wired in series = 32 ohms. Two 32 ohm cabs in parallel = 16 ohms). Some Marshall heads are designed to work at 4 ohms without modification. Check your particular amp to make sure you don't operate it at a lower impedance than it was designed for ... otherwise you'll be buying a new output transformer in the near future!
