Description More info Reviews  
Extremely high quality instruments available at entry level prices, and suitable for everyone from beginners to professionals, the versatile range represents unbelievable value for money.

The TRBX504 is a standard 4-string bass that has been specifically designed to give the biggest choice and greatest control of tone possible. Its mahogany body has been carefully contoured to reduce weight while maintaining a sleek modern look and comfortable shape. Playing is made easy by the super-smooth neck whose 5-piece composite construction also adds strength and looks great.

Several precisely engineered areas are worthy of note including the heavy-duty die-cast bridge which is designed for optimum string spacing and vibration, and set very close to the bottom of the body for perfect distribution of weight. There's also the durable plate-mounted jack socket and, at the other end of the instrument, the tuning pegs which are positioned to ensure a completely straight string from head to nut to bridge, reducing lateral tension to improve intonation and tuning reliability.

A unique feature of this model is the built in pre-amp which can be switched on and off as you play with no noticeable volume change. The passive sound can be shaped using master tone and balance knobs and is full and versatile enough to be used for any type of music, but is particularly suited to genres that don't need a huge low end. In active mode (i.e. pre-amp is ON), the tone is fuller and can be further manipulated with a 3-band EQ, but it requires a 9V battery to operate - there's a little LED on the back of the bass that will light up when the battery is nearing the end of its life, so you won't be caught out!
