If this project goes well enough, Slash won't be using that amp for much longer!

Another video blog on the Marshall website has revealed more progress in the development stages of Slash’s recently-announced amp head – the Marshall AFD100.

The head, which is still in its early production stages, is set to be a replica of the amp Slash used during the recording of Guns N’ Roses’ rock classic, ‘Appetite For Destruction’ – an amp which has since been lost in time.

This latest video update, number five so far, sees Slash and some of the R&D team at Marshall discussing the type of output tubes the amp should have and (rather disappointingly) which amp it should be based on.

This hints that the AFD100 may turn out to be merely a signature version of an existing head just with some custom tubes thrown in as opposed to a totally new amp.

This is early stages though, so we’re trying not to cast too much judgement just yet!

The story behind the amp Slash actually used on Appetite For Destruction is a bit of a complicated one. There are a few versions of the story floating round in Internet land, some of which are not even in the right ballpark.

The most persistant one, and the one with the most credence, is that the head that our curly-haired friend ended up using was an old 1959t Super Tremolo, modded by an amp tech by the name of Tim Caswell.

The tube-driven tremolo unit was removed and modded to add another gain stage to the circuitry.

Before hitting Slash’s hands in the studio with GNR, it was used by George Lynch while he was on tour and then rented out by Slash before AFD’s recording. That’s right, the amp used by one of the world’s most famous bands on one of the most famous records in rock history was just a rental from a guitar store.

Though story has it that when it came time for the band to record AFD, the amp was already out on rental, so Slash had the store mod another 1959t in the same way.

Since then, both those amps have been lost to the sands of time – enter Marshall’s AFD100 head. Hopefully Marshall and co. will see the light and decide not to base this off a JCM800. There’s already a plethora of those amps, signature or otherwise, out there available.

Even though the choice of 6550 tubes instead of the standard EL34s would give such an amp that bit more bite and bring it closer to that classic tone, it still wouldn’t be the same.

Fingers crossed that the next video update will bring slightly more promising news – I’m not calling it quits on this one just yet!
