real amps, each read from its schematic, ready to send to your Helix LT.

If your modeler has a mic input, four sends and returns and a separate PHONES knob, you have a Helix Floor. If it is a 3U rack, read the Helix Rack guide. The sound engine is the same across all three.

five things that explain almost every problem.

  1. 01

    footswitches that seem dead are in the wrong mode.

    The footswitches do not have fixed jobs. What they do depends on the mode. To change mode, press FS6, marked MODE.

  2. 02

    save, or you lose it.

    Nothing is saved until you press SAVE twice. Until then, an “E” beside the preset name marks it as edited. Change preset while the E shows and the edit is lost, with no warning and no undo.

  3. 03

    the cab block goes off when you feed a real amp.

    Cab block ON into anything full-range: headphones, an FRFR speaker, the desk, your computer. Cab block OFF into anything that ends in a real guitar speaker. A cab block is a speaker simulation. Into a real cab it stacks two speakers. Left off into a full-range system, you hear a raw amp with no speaker at all.

  4. 04

    one volume knob moves every output.

    The LT has one volume knob for every output, headphones included. They all move together.

  5. 05

    four amps in total, and no more than two on either path.

    Four in total, and no more than two on either path. A wet/dry/wet rig hits the two-per-path half of the rule first.
