Bogren Digital Ampknob BDH 66o6 Plus 1.2.118 — Mac build

Version 1.2.118 of Bogren Digital Ampknob BDH 66o6 Plus doesn't come with a public changelog, so what you get is a refinement of the same straightforward idea: a guitar amp simulation that keeps the controls minimal. The main switch still lets you shift from a tight, restrained sound to something saturated and energetic, and the pedal switch on the front panel is still there to add another layer of character. Nothing has been added or removed from the core workflow.

The plugin runs on macOS 10.13 and later, with full support for both Apple Silicon and Intel 64-bit systems. It's part of the AmpKnob BDH line, designed for guitarists who want more energy and presence without wading through a deep signal chain. The interface hasn't changed—it's the same simplified panel, English only, no new controls or presets to learn.

If you already know the 66o6 Plus, this version keeps the same character. If you're new to it, the pitch is simple: one main character switch, a pedal toggle, and the result is a tone that can go from polite to aggressive without needing extra routing or EQ. The install process hasn't changed either—follow the included instructions for setup and activation, and you're set.

Ampknob BDH 66o6 Plus fits into a specific corner of the amp sim world: the one-switch, no-fuss zone. It doesn't try to compete with deep, multi-amp suites like Neural DSP Quad Cortex (the plugin version) or IK Multimedia Amplitube 5, which give you signal chains with dozens of pedals, cab sims, and mic positions. Those are for when you want to build a sound from scratch. The 66o6 Plus is for when you already know the sound you want and just need to dial in the intensity.

Compared to something like the STL Tones Tonality series, which also offers curated tones from known producers, the 66o6 Plus is more limited in scope. Tonality plugins often give you a handful of presets per amp model, plus some basic EQ and effect slots. The 66o6 Plus gives you one character switch and a pedal. That's it. But that limitation is the point: less time tweaking, more time playing. Against a free option like the NAM Player, which loads arbitrary captures of any amp, the 66o6 Plus offers a specific, consistent character that's been sound-designed by Jens Bogren. With NAM you can get any sound, but you have to hunt for it. With the 66o6 Plus you know what you're getting the moment you flip the switch.

Start with the tight switch at low gain for a mid-focused clean baseline

Start with the main switch in the tight position and play a few riffs at low gain. This gives you a baseline of the amp's mid-focused clean character. Then flip the switch to the saturated side and play the same thing again. The difference is immediate, and hearing it against your own playing makes the character change easier to internalize than jumping straight to high gain.

Try the pedal switch with both positions of the main switch. On the tight setting, the pedal adds a push that works well for single-note lines. On the saturated setting, it can push the sound into fuzz territory depending on your input level. Use your guitar's volume knob to feel how the plugin responds to cleanup—the 66o6 Plus behaves more like a real amp than a distortion pedal in that regard.

Record a dry DI track first, then re-amp it through the plugin while adjusting the main switch and pedal on separate takes. This lets you A/B the settings without having to play exactly the same part twice. It also lets you hear how the plugin shapes the attack and sustain without your playing dynamics changing the sound.

An audio interface is required for the 66o6 Plus to process your guitar input

Do I need an audio interface to use it?
Yes, the same way you need one for any amp sim plugin. The 66o6 Plus processes an input signal, so you need a way to get your guitar into the computer. A direct box or the instrument input on your interface works fine. Without one, you won't get a usable signal.

Does it work in any DAW?
It loads as a standard VST3, AU, or AAX plugin, so any DAW that supports those formats—Logic Pro, Ableton Live, Pro Tools, Reaper, Cubase, Studio One—will see it. No special wrappers or host software required.

Does it include cab sims or do I need to add my own?
The plugin handles the full amp sound, including cabinet emulation, so you don't need an external IR loader or cab sim. You can still add your own if you want, but the out-of-box sound is meant to be ready to record.

Can I use multiple instances at once?
Yes, as long as your system handles the load. Running several instances for different guitar tracks is how most people use it in a mix. Each instance can have its own main switch and pedal state, so you can have a tight rhythm tone on one track and a saturated lead on another without any conflict.

Is it for a specific music style?
It was designed for metal and hard rock, but the clean-to-saturated range means it can work for rock, punk, stoner, or even some indie tones if you keep the gain low. The mid-focused character makes it cut through a mix well, which is useful for any genre where the guitar needs to sit clearly in the midrange.

Fitting it into a larger setup

If you already use a channel strip or preamp plugin before the 66o6 Plus, keep the gain staging clean. The plugin expects a healthy instrument-level signal, not a pre-distorted one. A little saturation can work, but too much will muddy the character switch's range. Put the 66o6 Plus first in your guitar chain, then add EQ, compression, or reverb after it.

For re-amping, use a simple folder track in your DAW with the dry DI signal. Route the output to a track with the 66o6 Plus loaded and record the result onto a new track. This keeps your original DI untouched and lets you try different switch positions later without re-recording.

MacOS-specific: if you use Logic Pro's Pedalboard or Guitar Amp Pro, the 66o6 Plus replaces both in one instance. You can use it as a direct substitute for the amp section of Logic's rig, but keep in mind the 66o6 Plus doesn't include separate pedals or modulation effects. Pair it with Logic's stock delay and reverb sends for a complete sound without third-party plugins.

For live tracking, set the 66o6 Plus on a monophonic track and disable any latency-inducing plugins in the session. It's not a zero-latency plugin, but at standard buffer sizes (128 or 256 samples) the response is close enough to an amp feel for most players. If you're monitoring through it while recording, keep the direct monitoring off on your interface to avoid hearing the dry signal alongside the processed one.
