KLOS Apollo IV Custom Bass - Charcoal finish - Paulownia Body/Carbon Fiber neck - New EMGx PU's and 3 band EQ - Ultra light weight pounds - One of the lightest basses available

KLŌS's reimagined Carbon Fiber 4-String Bass. With a wooden body and carbon fiber neck, you’ll get an experience unlike any bass on the market. The consistent structure of the carbon neck allows you to tune less and play more. Every fret sings, reverberating vibrant, clean tones through the wooden body anywhere you want to play it.

Unrivaled Playability

Because carbon fiber is a much more stable material than wood, you can set your action with lower string height. Experience unmatched playability, speed and ease of use with a PLEK’d carbon fiber neck.

More Stability

Carbon Fiber basses are designed to stay out of the case, ready to be played at all times. No more need to hide it in a case, under your bed, in a humidified room. Warping, twisting, high action, and fret sprouting simply won’t happen.

Improved Durability

Carbon fiber has 60x the strength to weight ratio of steel. From the headstock to the heel, this neck won’t wear down with time or get damaged from travel and abuse.

The B30EQ System is designed for contouring the bass, mid and treble frequencies of bass guitar. The B30EQ features single-pole filters for broadband equalization at 6db per octave. Often the broader single-pole filters are preferred for musical instruments because they are less selective, easier on the ear, and sound more “musical”. Paired with passive Volume and Blend pots, the B30EQ system pairs perfect with your EMG active pickups. These EQs have been a favorite of top Bass builders for years, now available direct to you.
