Pedals that stack with the Hartke LH1000 Bass Head

ProCo RAT 2

A RAT 2 out front gives the LH1000's punchy, warm preamp the low-gain, cutting distortion it doesn't produce on its own.

Ashdown Geezer Butler Signature

Push the LH1000's punchy, warm preamp with the Geezer Butler's doom-voiced distortion and the low end stays defined.

Black Arts Toneworks LSTR Fuzz

The LH1000's punchy, warm preamp gives the LSTR's scooped, sludgy fuzz a tighter, more defined front end.

MXR Phase 90

Phase 90's classic swirl colors the LH1000's punchy, harmonic bass tone after the preamp rather than stacking onto its gain.

Pigtronix Philosopher's Tone Micro

Run the Philosopher's Tone before the LH1000 for boutique sustain and midrange-forward compression before the bass head's own punchy preamp reacts.

Boss RV-5 Digital Reverb

Keep the RV-5's reverb in the LH1000's effects loop, after its own punchy, tube-warmed preamp shapes the bass tone. — goes in the amp's FX loop (or last, into a clean amp)

Meris Polymoon

Polymoon's dynamic, stereo modulation and delay textures belong in the LH1000's loop, downstream of the head's own clear preamp. — goes in the amp's FX loop (or last, into a clean amp)
