HeadRush firmware 5.1.0 added a new ReValver amp, a graphic bass EQ, gain reduction meters, phase invert, and four other changes nobody wrote about. Every headline went to the capture support. Fair enough, that was the big news.
The capture support is one block in one rig, though. These other changes are the things you touch every time you build a patch, and a couple of them fix complaints owners have been making for years.
The August firmware that brought NAM aboard listed them all on a single page of release notes, one line apiece, no fanfare.
That pairing matters more than it sounds. HeadRush built 48 cabinet IRs specifically for the ReValver models, one per amp, precisely so there is a sane starting point before you go hunting. Load the amp, get the cab it was voiced against, then wander off if you want to.
The name follows the house pattern. HeadRush already ships a SuperClone called Lead ACM800, so ACM is their standing stand-in for a particular British initialism, and the 900 tells you which decade of that family you are getting.
Phase invert is the bigger deal, and it lives in Advanced Block Edit. Run two signal paths in parallel, or blend two IRs on a single block, and phase cancellation quietly hollows out your low end. You hear it as thinness and blame the amp.
The case that catches people out now is running a bare NAM capture alongside a modeled amp on a parallel path. Flip one side and listen. If the bottom end comes back, you found it. Before 5.1, the only fix was reordering blocks and hoping, which is a miserable way to spend an evening.
The Graphic Bass EQ joins the EQ category, which bass players have wanted since the Prime launched. Nothing exotic, just fixed bands you can shove around without hunting for a frequency.
The BBD Delay also picks up CLASSIC and MOD modes. Bucket brigade circuits drift and smear as repeats decay, and the two modes split that behavior into a straight analog repeat and a modulated one, so you stop having to bolt a chorus block onto the end of your delay to get the wobble.
Silent tuning between songs used to mean assigning a footswitch you could not always reach, or tuning loud and apologizing to the front row. Now it is heel down, tune, toe up, play.
The drum machine also takes commands over Wi-Fi through HeadRush Remote. Remote is not an app, which trips people up constantly. It is a web page served by the board itself, reachable at HeadRushPrime.local, HeadRushCore.local, or HeadRushFlexPrime.local from any browser on the same network, and it wants firmware 4.0 or higher plus a screen of seven inches or more.
So a tablet propped on your cab becomes the drum controller, and you get the whole kit list in front of you rather than three entries at a time on the pedal screen. There are 16 kits and 134 styles across 15 genres in there, built from Alesis Drums and BFD samples, with fills, accents, and transitions on footswitches. The looper syncs to the drummer and to external MIDI clock, so a solo set stays in time without a click in your ears.
The clock, timer, and stopwatch sound like filler until you have played a festival slot with a hard cutoff. A running timer on the board beats squinting at a phone taped to a wedge.
Underneath all of it sits a line about minor bug fixes and DSP performance enhancements, which is the sort of thing worth caring about when you have just spent 30 percent of your processor budget on a single capture.

A new amp arrived with its cabinet already matched
The 90 ACM 900 lands in the ReValver amp category, and it ships with a matched cabinet impulse response rather than leaving you to guess.That pairing matters more than it sounds.

Metering and phase controls close two old gaps
Every compressor on the board now shows gain reduction. All six of them. Setting a compressor by ear on a loud stage is guesswork, and gain reduction metering on every compressor turns it into something you can read at a glance.Phase invert is the bigger deal, and it lives in Advanced Block Edit.

The stage features got the smartest changes
Roll the volume pedal all the way back, and the tuner engages by itself.
