What started as Micro Booster has evolved into a clever preamp pedal!

SOLO Boost Master Preamp is a unique designed clean FET buffer/booster pedal with added control over your solo tone shaping. Encased in a rugged but tiny aluminium box, this high quality built circuit has audio mastering virtues. Check it out!

FET AUDIO CIRCUIT

A FET implementation derived from original vacuum tube audio amplifier circuits, calibrated for the best sounding clean boost. When circuit is not engaged, the signal is in True Bypass.

TILT-EQ TONE STAGE

Borrowed from hi-end audio, this tone control allows mild corrections by boosting lows while cuting highs and viceversa; pivot frequency point is set at 1KHz.

AUDIO MASTERING CUT FILTERS

Cut a little to reveal more! Designed from an audio mastering perspective, these switches cut delicately, each from selected frequency spectrum: lows, mids & highs.

MID SWEEP CONTROL

When Mids Cut switch is enabled, this powerful control sweeps the cut frequency along with varying the amount of cut. It makes a big difference at it's maximum setting.

OPTIMIZED FOR LOW NOISE

This is not a volume control, but a bias for the amplification stage. Set and use only the amount of gain needed - you will always end up with the minimum possible noise.

FROM BUFFER TO BOOSTER

Set Gain Control to minimum to use it as a high quality FET buffer. If needed as booster, the circuit can pump-up up to +20dB of clean signal amplification.

SOLO Boost Master Preamp

Designed with an audio mastering approach, this pedal allows you to lightly cut boomy or harsh frequencies while boosting your solo tone.

SBMP-1 SOLO BOOST MASTER PREAMP

GIVING CONTROL OVER YOUR BOOSTED SOLO TONE

The SOLO Boost Master Preamp is based on a clean FET buffer/booster circuit, with simple to use controls, which, used in combination, reveal their real power of sound shaping. Encased in a rugged aluminium box, this minion takes little space on any pedalboard.

A variable gain stage allows a flat raise of the input signal, starting from unity gain (buffer level) and going up to +20dB of amplification, enough to either saturate a following drive stage or boost the signal when placed after. A Tilt-EQ active circuitry borrowed from hi-end music pre-amplifier design may be used to add minor corrections over buffered or boosted signal. Left in the middle position, this control does not alter the sound. On top of that, three additional cut filters can delicately act upon selected frequency spectrum, to further contour audio signal. The mid-cut section has the most powerful effect in conjunction with the variable Mid Sweep control, which selects the cut spectrum as well as the amount of cut.

SOLO Boost Master Preamp raises the bar in audio small signal amplification, rendering a pristine and warm sounding guitar tone. It complements well any instrument's magnetic pickup, but it can also be used to warm-up the powerful and sometime sterile sounding active pickups. It works well with both, electric guitars and bass guitars.

How we ship?

 

Shipping worldwide from Romania/EU

We ship worldwide if your country is supported by carrier - Romanian Post - using International letter mail service with acknowledgement of receipt (A.R.) with Tracking Number, which is a small package economy service. If your country is not supported or has an extra shipping fee, we will let you know before shipping. Here is what you need to know about shipping:

  • We ship fast, from stock, no longer than within 2 business days from purchase date, unless otherwise notified by email.
  • We will ship the package to your Paypal recorded address. Be sure is the correct address, or make a note into the transaction comments, if you want the package delivered to a different address.
  • We record carrier and tracking information under Paypal transaction details and this information is also available in YOUR Paypal account.
  • While on Romanian territory, parcel can be tracked on Romanian Post.
  • In transit, parcel cannot always be tracked, although you could try this third party tracking system.
  • When parcel enters the destination country, it can be tracked again on the corresponding national Post's website - if such a service is available (i.e. www.usps.com for USA or www.royal-mail.com for Great Britain, etc.).
  • Based on shipping history, we estimate that delivery may take around 15 business days to reach destinations in USA and European countries, but many times it will take less.
  • For remote destinations such Australia, South America or Asian countries shipping takes longer. We cannot estimate, nor guarantee, but some parcels were confirmed delivered within less than four weeks.
  • Delays may be expected before, during and after major holidays like Christmas, Easter, national day offs, etc.
  • If you would like to pay for faster UPS or DHL services, please ask us for exact quote for your address, although it might not worth it.
  • We do not put any selling papers in the package nor declare value, but buyer is responsible for customs fees, if charged by each country's authority. EU destination countries will definitelly NOT charge custom fees because we ship from within European Union.
