They say:

The AMA has been created to provide the most exciting experience to all the sonic adventurers out there who love a gently modulated and oscillating spring reverb in front of a bit crusher!!

The AMA V.2 offers up to 4 different control parameters for the reverb (OSC, MIX, REVERB and RAMP) and 2 for the re-worked and now more musical bit crusher which is still placed after the reverb (RESOLUTION and SAMPLE RATE).
Note: About the bit crusher, there is also an internal trimmer which controls the effect's gate. We suggest to leave that as it comes from the factory.

OSC
One of the new features offered by the V.2.
In the first version, the reverb oscillator was only switchable (ON/OFF) and it was strictly related to the decay. Now things have changed: the OSC knob allows to decide how much oscillation has to be noticed on the reverb tail, going from no oscillation at all (OSC knob fully counterclockwise) to the as wonderful as noisy self-oscillation mode (OSC knob fully clockwise).

MIX
The MIX knob controls the balance between the dry and wet signal.
Turning it clockwise, the percentage of reverberated signal will be more noticeable (and viceversa).

REVERB
The REVERB knob controls the decay’s length.
Turning it clockwise, reverb tail will become longer (and viceversa).

RAMP
One of the most exciting feature of the AMA V.2.
The RAMP footswitch is related to reverb's oscillator and its work speed depends on the OSC knob setting: more closed will be the OSC knob, slower will be the oscillator ramp (and viceversa).

CRUSH
That's the position of the toggle switch which allows to engage the bit crusher circuit placed after the reverb.

RESOLUTION
The amount of the oscillation pulse. Turning it clockwise, pulses will be wider and signal will be noticed as less crushed (and viceversa).

SAMPLE RATE
Bit crusher internal oscillation frequency.
Turning it clockwise, the oscillation will be more focused on high frequencies and the bit crusher will be generally noticed as brighter.

EXPRESSION INPUT
Another new feature offered by this new version of the AMA is an expression input connected to the sample rate, which allows to bypass the knob and controlling the frequency's cut by using an external expression pedal (10k value recommended - so most of the expression pedals on the market).

The AMA is a true bypass pedal: It's a switching system managed by soft switch + programmed relay.

Power: 9v center negative. Current draw: 100 mA minimum

Worked perfectly for draining oil from zero turn lawnmower. Even cons with a spare inlet plug

1999 BMW 528i Fit and works like Original BMW-Pleasantly Surprised
1999 BMW 528i M52TU Engine. Pleasantly surprised and impressed. Everything fit as it should. Yes, one connector pipe took a bit more pressure to get it to "click" and lock, but it did click and lock..and better tight to insure no vacuum leak. Definitely works well and stopped the vacuum leak that old system had. Would recommend especially since price point might lead one to think that quality is not that good, but I'm glad I didn't spend any more on something else. Highly recommend.

Test fit to make sure it connects
When I revived it I thought it had looked a little too small until I compared it, I test fitted it and at first I thought it was a tad bit bigger but realized the more I pushed it in the more it went very tight fit and my car is running healthy. Installation is a pain but go to YouTube and search the “” the 50’s kid”” Who has two methods to getting them on, I went the intake removal route to replace additional parts.

Cheap Replacement
These are an easy replacement for anyone who owns a BMW m52/m54 engine that has PCV issues. My car was burning about 1 quart every 1,000 miles. The parts are direct fit and install fairly easy. If there is resistance, lube the hole or o-ring up with some grease and it will slide in easier. Took me about 2 hours start to finish. My mechanic recommended that I remove the intake manifold to do the job. I don’t see how you could do it without removing the intake manifold. These parts probably won’t last as long as true BMW parts but on a 20 year old car I don’t see the benefit in using genuine BMW parts. Cheap stuff will suffice; worst case it doesn’t last quite as long.

NOT TOO HARD TO INSTALL...
This CCV kit seems adequate. People say that because the hoses supplied with these kits are more brittle than the genuine BMW parts, these are tough to install... But they're really not. The ends on these hoses SWIVEL and you can sort of eyeball which way you need the fitting to be pointing BEFORE you put them on your manifold... They swivel, but they're tight and it takes a little force to turn them. ALSO, a little dab of silicone gel or a spray of silicone out of the can, into the fittings on these makes a world of difference when clicking them on... For the price, I highly recommend the kit.
