However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 3 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 60 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 3 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

Clean Boost Effect

Supro’s SP1303 Boost Pedal is a J-FET based pedal design that delivers up to 20dB of gain without adding any unwanted background noise. The pedal offers a straight forward and effective boost that stays sweet and clean on all settings, no matter how hard it’s pushed with other pedals earlier in the chain. The Boost effect remains frequency linear, even when the gain is adjusted, this allows the boost to be used at the desired level without losing tone or the need for EQ adjustments.

Bright and Dark Modes

The pedal’s preamp also features high and low pass filter options that can be accessed via the 3-way toggle switch. The toggle switch has three different modes; a bright mode, a flat mode, and a dark mode. The bright mode enables a 6dB/octave high pass filter that thins out humbucker guitars when adding boost to increase sparkle and prevent any mud. The dark mode enables a 6dB/octave low pass filter that fattens up single coil guitars when adding boost to increase warmth and prevent harshness.

TRS Port for Expression Pedal

The Supro Boost features a TRS port in order to attach an expression pedal to control the boost’s volume knob. This turns the Boost Pedal into a high-fidelity, active volume pedal with user-adjustable minimum and maximum settings. When the expression pedal is in use, the boosts on-board volume knob sets the maximum value while a user-adjustable, internal trimmer sets the minimum volume.
