About the Marshall SL5 amp:

The Marshall SL5 is Slash’s signature Marshall combo. It is an all valve, 5 watt, two channel amp. It’s powered by 3 x ECC83s and 1 x EL34 power tube. It features a simple shared, three band EQ.

In addition, the Marshall SL5 has a shared presence control for even more tone sculpting. The Marshall SL5 was created shortly after the AFD100 and has that distinctive Slash tone. It was designed as a more accessible amplifier for home or studio use.

The Marshall SL5 features a quality custom-voiced digital reverb that has an on/off switch and a channel shared control. The single volume control on the Clean channel takes you from authentic Slash clean to Marshall style crunch. While the Overdrive channel is made up of a Volume and gain.

It absolutely nails the A.F.D. sound.

Both channels have of course been looked over, and signed off, by Slash himself.
