INSIDE FATHOM II

What you get.

Modern Engine. Four gain stages, with tighter control of low end between them.
RIFF GATE. It's keyed from your clean DI, so stops are dead silent at full gain and it stays open through fast tremolo picking.
Overdrive + chainsaw pedal. OD TIGHT cleans up palm mutes and OD BODY puts the weight back.
27 level-matched factory rigs. They run from 2.5 BM Tremolo (E) to 2.5 OSDM Chainsaw (D) and 2.5 Tampa Death (E).
Dual cabinets. 15 IRs are included. You can also drag in your own WAV or AIFF files.
DOUBLER and FIZZ. DOUBLER gives a double-tracked wall that holds up in mono, and FIZZ removes harsh top end at the frequency you pick.
ECO / STD / HQ. Track light and bounce heavy: HQ RENDER does every offline export in HQ, and switching modes doesn't change latency.

FROM A PLAYER

“I'm absolutely blown away by FATHOM II! I've already managed to dial in the guitar tone I've been looking for, and I'm seriously impressed with how powerful and versatile this plugin is. It sounds fantastic!”

FREE RIGS

Free preset pack by Erymanthon Seth

Three FATHOM II rigs from Erymanthon Seth, one for each of his main bands: Apocalypse, Feralia and Teratum. He made them for his own playing and is sharing them for free.

Apocalyptic Chorus. IRON amp with chorus and reverb. A big, heavy sound with a Gothic tint for rhythms and leads.
Feral Tremolo. GRAVE amp into the chainsaw pedal. Bright and aggressive, for tremolo picking and arpeggiated chords.
Thrash Kommando. OBSIDIAN amp with overdrive, chainsaw pedal and RIFF GATE. Very tight, for fast riffing with high-output pickups.

FAQ

Questions.

Is there a free trial?

Yes, 14 days on Windows. It's email only, with no card needed. There's no trial on Mac.

Does it work on Mac?

Yes. Works on Mac (AU/VST3, macOS 10.15+), on both Intel and Apple Silicon. The first time you open it, macOS asks you to approve it once in security settings. There's no Mac trial.

Will my old projects sound different after updating?

No. Projects saved with earlier versions open at STD quality, with the new features off and the legacy amp engine kept. To hear the new processing, turn on MODERN ENGINE or load a factory rig.

Can I use my own cab IRs?

Yes. Drop a WAV or AIFF onto either cabinet slot, then use < > to step through the other IRs in that folder.

Is it a copy of a specific amp or album tone?

No. The amp voicings are my own algorithmic designs. I don't claim any artist endorsement or album-tone reproduction.

Plug in a DI and try it for 14 days, or buy it once for $29.

Updating from an older version?

Projects and rigs saved with earlier versions open at STD quality, with HQ RENDER, MATCH BYPASS, DOUBLER and RIFF GATE off, so they sound the same as before. Older saved rigs retain the legacy amp engine. Enable MODERN ENGINE on the amplifier page or choose a factory rig to try the new processing. Factory rig selection preserves your input and output trims, and LOCKS (next to UNDO/REDO) keeps any other section you choose.

New in 2.7.0: a rack-hardware design, the amp page opens first, and the amp picker and LISTEN & SET sit in the top bar. Read the 2.7.0 release notes.
