Maker: JAM Pedals

Model: Boomster

Condition: New

 

Description: 

With its musical response and increased headroom the Boomster mk.2 aims to redefine the quality standards of the buffer and booster genres. Extensive testing and comparison sessions with most of the appropriate chips currently in production, resulted in us opting for the hi-fi-grade Texas Instruments® OPA 2132 chips, which deliver effortless fidelity and lushness across the Boomster mk.2's different functions.

Our mission with the mk.2 version of the Boomster was to elevate it into a well-rounded boost pedal encompassing all the necessary features and functions contemporary musicians have come to expect, as well as to offer a standalone buffer that not only sounds great but also feels right under the hands, making it an indispensable tone component of any rig.

Mission accomplished!


The Boomster mk.2 comes loaded with:

• selectable true or buffered bypass via internal dip switches (see schematic)
• an expression pedal input to use as a volume pedal
 3 minutely tuned voicing options
 momentary / latching operation
 9-18V power-input range for variable headroom


Booster function:
Get up to  16db of clean unadulterated boost. Place the Boomster mk.2 after your drive section for a volume increase or hit the front end of your amp or different drive pedals to introduce an added gain-staging option! The 3 voicing options available are designed to help you precisely sculpt your tone and match different guitars, pedals and amps to one another.

We have carefully tuned these to a guitar-friendly range but have tested them to be useful with all sorts of instruments:
• the top position attenuates the top end (control by how much via set-and-forget internal trimmer)
• the middle position retains a flat, full-range response

• the bottom position introduces more mids (control by how much via set-and-forget internal trimmer)

*When the Level knob is all the way to the left (closed) the Booster’s output level is at unity gain.


BUFFER BYPASS FUNCTION:

The rigorous R&D process employed for the development of the
buffer inside the Boomster mk.2, accomplished the 2 main traits we feel make for a great buffer;
With the Texas Instruments® OPA 2132 chip powering the buffer the Boomster mk.2 will:

• instantaneously bring back frequencies compromised over long signal chains, without the unwanted top-end harshness and compromised mids many buffers suffer from.
• successfully retain the original feel of the instrument, something very few buffers achieve.


VOLUME PEDAL FUNCTION:

Pair the Boomster mk.2 with any commonly available 10k passive Expression pedal and you have yourself a smooth travelling volume pedal starting from 0db at the heel position all the way to wherever it is that you have the L (level) knob set if the pedal is activated, or from 0db to unity gain when the pedal is OFF and in buffered bypass mode!

    Best electric pepper and salt grinder for a very reasonable price!I
    Color: 2-Speed Rechargeable Set with Base
    I've spent over $200 on salt and pepper grinders including very pricey manual ones and a name brand electric grinder which was costly and had a weak motor. I bought these expensive grinders thinking I would get a quality product by spending more money. Well, it was a waste so I decided to try this highly rated Circle Joy grinder and, so far, it works incredibly well! The high/low speed works exactly as expected and at high speed, it grinds really fast. The motor is powerful and does not feel like it's going to give up even when grinding salt or pepper at high speed and on the fine setting. It is easy to refill, holds a long charge and just simply works. Buy this. You will not be disappointed... and say goodbye to having to wash your hands everytime you flip a raw piece of meat or chicken to salt and pepper when using a two hand manual grinder.

    Works well.
    Color: 2-Speed Rechargeable Set with Base
    Close to 5 stars. Only minor complaint is somewhat shorter battery life then expected. But since it is rechargeable, not a big deal. Like the adjustable grinder and the clear container so you can see how much it has.

    Great salt and pepper set!
    Color: 2-Speed Rechargeable Set with Base
    Great salt and pepper set! I love that it has a light that makes it easier to see how much is coming out. Very easy to use, easy to fill, nice selection of grind sizes. It is also nice that it has a base to hold it because there is a very small amount of salt that comes off the bottom so it keeps it from going on the counter while not in use - it's not leaking, just leftover residue from the grind you have just finished.

    They’re nice… if they work…
    Color: 2-Speed Rechargeable Set with Base
    I ordered four of these grinders and two of them broke down while a third never started up. I am honestly disappointed in the failure rate of these otherwise nice grinders. If only one grinder in a two-pack failed, I would’ve just taken it on the chin and moved on. But three out of four total is unacceptable. I like the way they look, and the grind speed and settings are nice. But there’s a serious durability problem they need to fix.
