Sims not (yet) reviewed on the site

While we strive to review all amps sims there’s still a number of amp sims and pedals out there developed by individuals or smaller, indie, less-known companies that’s not reviewed on this site as of yet. These range from full-blown sims to proof-of-concepts and experiments. Most – but not all – of these are freeware. Some are excellent but quality varies. To make it easier finding these here is a list (in random order) of some of the amp sims and pedals not mentioned anywhere else on the site.


Russian developer Vadim Taranov has been around for some time and established a solid reputation for doing good freeware and low-cost amp sims. For example check the free P.R.O.T.O Four. Also don’t miss his contributions to the HASR Freepack.
