A tonal variation of the pre rola 35 oz. magnet 55hz G12M bass cone, but with more lower mids, and creamier treble. This speaker uses a different Kurt Muller cone than the M55-PVC, and has less upper mids than that speaker. Awesome for Strat & Tele single coil pickup guitar players that want to fatten up their tone, as well as brighter Gibson style guitars. 24 hour Factory Break In (FBI) is now included on all speakers sold.

Who this speaker is for: Those requiring more low end than the M75.

A close recreation of the the pre rola 35 oz magnet 55hz G12M Pulsonic paper voice coil style speakers used until 1973. This speaker's tone is woodier, with more upper mids than the M55, but less treble and more bass than the BlackBack BM55 models. Basically it's tone sits between those two models. 24 hour Factory Break In (FBI) is now included on all speakers sold.

The 20w speakers are built to the original 1967 Kraft paper voice coil (PVC) specs. If sent too much power, they can spark or catch on fire. Due to this possibility, they are sold without any warranty, liability or guarantee. Once you mount them, they are non-returnable, period, no exceptions. It is strongly recommended you buy four of these for a 50w amp, and eight for a 100w amp. While I have never had one spark or catch on fire since 2011, there is the potential it could happen.

The 65w PVC speakers are built with higher temperature nomex voice coils and have a 1 year warranty. There is hardly any difference between the 20w Kraft and 65w Nomex voice coil speaker tones, but some clients feel the 20w models have a tiny bit more bass response. The 65w speakers do not spark or catch on fire.

Who this speaker is for: Those who want to sound like Paul Kossoff of Free.

Warm, detailed low midrange enhanced pre rola G12M 75hz guitar speaker with smooth overdrive and distortion tones. Great sound right out of the box due to factory aging, design and break-in procedures. This is a tonal variation of the G12M 75hz Pre Rola era "Greenback" that was used in Marshall stacks and combos, and many other British amps of the era such as Vox, Orange, Sound City, etc. 24 hour Factory Break In (FBI) is now included on all speakers sold.

This speaker is for: Those players who like the 25w G12M 75hz Pre-Rola tone with more lower mids and a creamier treble response than the M75-PVC.

Warm, detailed midrange enhanced guitar speaker with smooth overdrive and distortion tones. This is a superb tone and sound recreation of the 60’s G12M 20w Kraft paper voice coil era "Greenback" that was used in Marshall stacks, BluesBreaker combos, and many other British amps of the pre 1973 era such as Vox, Orange, Sound City, etc. They have a very pleasing upper midrange voice that cuts through the mix without being harsh.

Who this speaker is for: Those players who want the classic G12M 75hz Pre-Rola tone from the mid 60Õs through 1973.

Same speaker as the M75, but with a large dust cap. The large dust cap smoothes out (rolls off) the highs, and makes the treble silkier on the top end, and adds a bit more bass response. The large dust cap model is similar in tone to a G12-65, but with the more authentic vintage Pre Rola type tone. It also handles higher gain better than small dust cap speakers, making it ideal for Dumble tone or high gain style players.

This speaker is for: Those players who want a G12-65 tone with more low end.
