The manual your modeller should have shipped with.
Gridleak Guides are independent, deeply-sourced manuals for guitar amp modellers — interactive control maps, signal chains, rig setup wizards, tone recipes and the troubleshooting references that don't exist anywhere else. A source on every claim.
One modeller at a time, done properly
Each guide is built by reading everything published about the device — not by paraphrasing the manual. A guide ships when we've exhausted the available sources, not on a schedule.
Nano Cortex
Captures, not models. The cab-sim rule, the rotary footswitches, and the four presets under your feet.
Open guideQuad Cortex
Scenes, the full four-lane grid, and Capture V2 — everything the Nano deliberately isn't.
Not started yetHelix
Floor, LT, Rack and HX Stomp. Blocks, the DSP budget, snapshots, and the routing nobody explains.
Not started yetAxe-Fx III
Four independent grids, Cygnus amp modelling, and the depth that puts people off starting.
Not started yetAxe-Fx II
Still gigged everywhere. Ares firmware, tone matching, and getting Axe-Edit out of your way.
Not started yetFM9
Most of an Axe-Fx III in a floorboard, and the DSP ceiling that comes with it.
Not started yetFM3
Three blocks of headroom and one amp block. Where the budget actually goes.
Not started yetFour rules, and we don't break them
Every source, then a citation on every claim
Manufacturer documentation, firmware release notes, dealer specs, professional reviews and thousands of owner reports — read in full, then cross-checked. Each fact carries where it came from and how well evidenced it is, and anything we can't confirm is marked unverified rather than asserted.
Version-stamped, because staleness is the real problem
Most gear coverage is written once and left. When firmware changes what's true, guides here say which release they're checked against and what older advice it invalidated.
Interactive where a table won't do
Clickable control maps, signal chains you can inspect slot by slot, and setup wizards that turn “what am I plugging into?” into actual settings.
Honest about what nobody knows
Reading every source shows you where they disagree. Where a manufacturer's own documents contradict each other, we show the conflict instead of quietly picking a side and looking authoritative.
