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 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 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 5 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.

Development of a Classic

The Roland Boutique TB-03 Bass Line, inspired by the iconic TB-303 Bass Line Synth, uses Roland's advanced Analog Circuit Behavior to replicate the authentic sound and character of the original TB-303. The TB-03 provides efficient control options including a four-digit LED display for enhanced programming and rotary dials to give hands-on control over tuning, cutoff, resonance, envelop mod, decay, and accent. The original TB-303 featured pitch and time write modes, however the TB-03 goes a step further and interprets a new step-mode and fine tempo control to give you more convenient access to the controls that you need most.

Increased Versatility

The Roland Boutique TB-03 Vocoder also functions as a high-quality 24-bit/96 kHz audio interface to provide a simple and effective way of recording straight to your DAW. With a choice of USB or battery power, the TB-03 functions just as well on the road as in the studio. 4 x AA batteries provide the TB-03 with sufficient power, or alternatively you can connect to a USB power source to utilise USB bus power.

External Instrument Connection

The TB-03 Vocoder includes MIDI IN/OUT ports along with USB, to allow control information to be sent between external instruments and devices. With the ability to use the CV/Gate output for connection and control of analogue gear and modular synths, the TB-03 makes an extremely versatile synth/ recording device. The level of control is also reversible, with the external gear having the ability to drive the TB-03s internal sequencer. The USB ports also features MIDI data connection between any PC or Mac when connected.
