— McRocklin

Four Uniquely-voiced Amps


With four profiles covering bright and airy, to rich and full. Bring out the sparkle in your guitar.


Punchy and smooth, with exceptional dynamic response. Based on a custom design for incredible versatility.


A boutique amp which can do everything from bold cleans, to edge-of-breakup. Turn on an overdrive pedal to make it Rock!


From tasty low-gain, to modern nuanced high-gain. The Gain amp is designed from the ground up to get the most from our drive pedals.

Strap in, let's drive


From Ripping tight, to Full Beast Mode. Attacker is the Drive to use when you want a fresh modern sound.


A modern take on an Overdrive icon. Our unique mod takes this classic drive to a new level.


A modded vintage Distortion pedal that's a banger for riffs.


With a broad mid range, this is the perfect drive for adding colour that cuts through a mix. Try stacking with other drives to get the most out of it.

Pre Effects


The first and only software Wah to replace McRocklin’s favourite hardware Wah pedal. From subtle to extreme, Wah has you covered.

Heatpressor: The multi-algorithm monster.

From punchy compression, to chest thumping boost, top end sizzle and much more. HEATPRESSOR is more than your average compressor.

An Octaver like no other.

Introducing SYNTH OCT A Synthesized octave-down companion. The sound of a wild night out with your best friends.


Add analog style modulation to your clean tones, or give your distorted tone a huge stereo image.

    During his streams, I tried copying his tone in NDSP and ended up just curling up in the fetal position crying. But now I have it all

    Polychrome is really nice. I have piles of plugins (Neural, Joey Sturgis, IK, etc.) and McRocklin's suite is a deal vs these other guys. And come on... McRocklin in a box!
