The Diezel Zerrer is a 2 channel preamp in a pedal that can be utilized in front of an amp as a distortion, as a practice amp, and a studio direct amp with aggressive tones and features that are synonymous with Diezel. There is a stereo headphone jack which allows the use of the Zerrer as a practice amp. In addition a stereo aux input providing the ability to plug in external backing tracks. The versatility of the Zerrer is second to none like having a Diezel head in a box that can be taken on the road for practicing, recording and playing live in front of any clean amp.FRONT OF THE PEDAL CONTROLS
- Channel 1 Clean/ Dirty – This channel features independent eq with a separate gain control to adjust the level of distortion for either crunchy rhythms or crystal cleans.
- Channel 2 Heavy/ Lead – This channel features more gain than Channel one. Making it ideal for aggressive modern rhythms and soaring leads.
- Master Volume – Like the Diezel amps there is a master volume to control the overall level of both channels.
- Presence Control – This controls the amount of sparkle or cut for both channels adding brilliant highs for killer clean tones as well as adding that extra bit of shimmer to your leads.
- Deep Control – This control adds girth to your tone. This is very effective when using the Zerrer in front of a clean amp that might be thin sounding.
BACK OF THE PEDAL CONTROLS
- Guitar Input – ¼ inch jack for plugging in your guitar
- Amp output – ¼ output into the amp
- FX loop – this allows you to plug any FX processor or FX pedal into the back of the Zerrer making the unit completely self sufficient for both Live and Studio use.
- Direct Stereo out – This output contains a high quality speaker emulator that allows you to record direct from the unit itself giving you all the tones offered in a Diezel amp.
- Stereo Headphone Input – ¼ inch input for any stereo headphones allowing for quiet practice or recording without the need for external speakers.
- External switcher input – The Zerrer also offers an external switch input that can be used with any toggle switch to turn on and off the unit. This allows the user to keep the unit in a rack or near the amp and still be able to switch on and off.

Not as good as I expected
When it first came, the box fell apart as I was taking it out, and a lot of some kind of dirt or sand kept falling out all over my table and floor. I had the take the entire thing apart and thoroughly wash it.
After drying age reassembling it, I tried it on my portafilter that came with my Breville Barista Express, but, somehow, it doesn't always make the tamping level. You would think with the ridge that rests on the side of the portafilter that it would force it to remain level, but, somehow, it doesn't, at least not consistently. It also has varying lengths (heights, or depths), and a single spring tension, so you may still over tamping or under-tamp. I was expecting it would have a censor that would just detect once it reached 30 lbs of force and cut off after that, similar to a torque screwdriver, but that's not what this is.
I'll still give it 3 stars because, despite the problems mentioned above, it at least produces some amount of consistency, even if that isn't measurable; but, I can't give it 5 stars because of those issues mentioned above.

This is the one.
Size: 58.3mm, Color: Black
As an el Supremo Coffee Geek, I've wasted money on lots of different tampers. Save your money and buy this one or it's equivalent. This thing is heavy duty, solid, well-made, self-leveling, tamps at 30 pounds and is fool-proof even for fools. Also, it's a palm tamper meaning more fun and more satisfying to use as you prep the puck for your morning buzz. Buy it. You will thank me.

Super easy to use and takes the guess-work out of getting even pressure on the grounds
Size: 58.3mm, Color: Black, Size: 58.3mm, Color: Black
I have been using a hand tamper for many years and have a good idea of the pressure I am applying to the grounds in the portafilter. I honestly considered spring tampers to be a bit silly. But this tamper really does take the guess-work out of pressing the coffee grounds. The shroud helps guide the press so that pressure is applied even and flat across the surface. With the manual tamper, there will be some play when pressing, or some unevenness in pressure. This is especially true when cranking out many espressos during a breakfast party with friends. Having the spring tamper makes quick work of turning out a lot of coffees with consistency.
There are no instructions for taking this tamper apart to clean inside, and you may not really need to do that very often. After each use, just pull back the shroud (the black piece that moves up and down) and wipe off the tamper (the shiny steel part). This will help prevent grounds from working their way inside. If you do want to take it apart, it’s easy. Pull back the shroud and unscrew the tamper. It will come apart into three pieces. Wipe the pieces off and reassemble. Super quick and easy.
This tamper is very heavy. My scale shows 656 g (about a pound and a half). It fits the portafilter exactly, with no slop. Just place on top of grounds and press!. Don’t even worry about pressure, just push down all the way. Overall I had fun using this tamper versus my manual one. And since I make myself a cappuccino very early in the morning, I don’t have to be very awake to get a good pack on the grounds and get my coffee fast!

It is heavy
Size: 58.3mm, Color: Black
Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.
