Slash

There is endless of speculation about the exact Marshall that was used for the Appetite For Destruction recording sessions. Most probably, the amp in question was a modifed Marshall 100 watts 1959T Super Tremolo, owned by S.I.R., a rental company in Los Angeles, and it was known as "Stock #39". The amp had been modded by Tim Caswell, who basically used the amp's unused tremolo circuit, with its additional pre-amp valve, to produce more gain. Also added to the amp was a master volume control.

The Jubilee head was released in 1987 to celebrate the 25th Anniversary of Marshall. It is heavily based on the JCM 800 of the time, featuring a very similar output section along with a new preamp. This amp is part of Slash's live gear since Guns N' Roses era.

One of the most famous Marshall amp and one of the most representative of Marshall sound. Slash mainly played on this head during the early Guns N' Roses years. "We changed out the tubes in this for 6550's, other than that, it's stock," Slash's guitar tech Ace says in this video at (7:30).

Slash used this amp for the clean sounds in the studio for songs like:

Paradise City My Michelle Sweet Child O' Mine Knockin' On Heaven's Door Estranged Yesterdays November Rain Live And Let Die Civil War Rocket Queen Coma So Fine

Slash uses Celestion Vintage 30s in his speaker cabinets.

The Marshall AFD100 is Slash's signature head designed to replicate the amp Slash used on Appetite for Destruction. "This is a limited edition," Slash's guitar tech says in this video at (7:00). "We usually start with all the settings around 6 and then dial in for the room," he said.

In the YouTube video "Nothing To Say, live in Melbourne," Slash can be seen using a Marshall JVM410H guitar amplifier head.

In the YouTube video titled "Slash and Zakk Wylde guitar duel/duet" by kingyshell, Slash can be seen using the Orange Rockerverb MKII 100-Watt Tube Guitar Amp Head.

The Marshall Vintage Modern 2466 100 watts head is an all-valve single channel amplifier with a choice of two dynamic ranges selectable by footswitch. Slash only used it with Velvet Revolver.

Slash uses Celestion G12M Greenbacks too in his cabinets.

First Marshall amp to bear the signature of an artist, the Marshall JCM Slash Signature is an authentic reissue of the classic 2555 Jubilee head that was released in 1987 to celebrate the 25th Anniversary of the company. Only 3,000 units of the Marshall JCM 2555 Slash Signature amp were made from 1996 to 1997 and Slash used it for all tours ever since...

In the 1988 Ritz performance video and a photo from the Donington show the same year, Slash is seen using a Marshall JCM 800 2210. These amplifiers were likely rented as substitutes for the Jubilee models, being the only other high-gain Marshalls available at the time.

Slash uses the Marshall 1960 BV 4x12 cabinet.

At various points in the video, Slash can be seen using four 4x12 Marshall stacked cabinets. They don't have the Marshall logo, but you can clearly see that they are probably Slash's well known silver colored Silver Jubilee cabinets. Correct me if I'm wrong please! Times where the cabs can be seen clearly: 2:03 - 2:18 (right) - 2:21 (left) - 3:02, and many other times in the video.

In this video we see Slash talking about his experience with music, strings and playing with his signature combo.

"... the same tone I used with a 50s Fender Twin..."

Magnatone is announce the release of the Slash Signature SL-100 Head and SL- 4x12 speaker cabinet.
