Fulltone Supa-Trem Jr Tremolo

I picked up the Harley Benton Custom Line CS-5 Compressor to add controlled sustain and a tighter clean tone to my rig - I wanted something uncomplicated that I could trust on rehearsals and small gigs. It’s a three-knob compressor - Level, Attack and Sustain - in a metal enclosure with true bypass, and that straightforwardness is exactly what drew me to it; I don’t always need a thousand parameters, I need something that sits in the chain and gets the job done.

First Impressions

My first impression was that the CS-5 feels a lot tougher than its modest price implies - the housing is heavy-duty and the footswitch has a satisfying, positive action that felt roadworthy right away. The three knobs are large enough to tweak on the fly without fuss, and the LED is bright and easy to see under stage lights; immediately I appreciated that it intentionally keeps the control set minimal. The unit’s footprint is a little larger than some mini-pedals but it still tucks on a pedalboard without stealing too much space.

Design & Features

The CS-5 follows the classic compressor template - Level, Attack and Sustain knobs - which makes it intuitive whether you’re coming from a studio compressor or any stompbox compressor. The pedal offers true bypass and works from a 9 V battery or a 9 V adapter, so integration into an existing board or a quick rehearsal setup is painless. The chassis is metal and feels like it can take a bit of stage abuse, and the I/O is standard 6.3 mm jacks so there are no surprises when patching in.

Playability & Usability

Using the CS-5 is refreshingly simple - I dialed the Attack back for funkier choppy rhythm playing and brought Sustain up for glassy, sustained single-note leads. Level lets me match bypass volume without having to retweak amp settings, which is handy when switching between rhythm and lead parts mid-song. The knobs have a predictable response and the pedal behaves consistently across guitars - from single-coil Tele-style tones to humbuckers - so it’s easy to remember settings between gigs.

Real-World Experience

I used the CS-5 in rehearsals, home practice and one small club gig; in each context it did what a compressor should do - even out dynamics, make clean parts sit in the mix, and give leads a bit more sustain without sounding obviously processed. For clean arpeggios and country-style lines it smoothed transients and added that “glue” I wanted; for funk it gave the pick attack more consistency. At higher sustain settings you do start to hear a noticeable squashing effect - which can be musical if that’s the sound you want, but it’s something I watched for when I needed note clarity. The pedal is quiet in general, though if you over-crank Sustain you can coax some increase in apparent noise and pumping, so I tended to use moderate settings live.

The Trade-Offs

The CS-5 is not a Swiss Army knife - it does not have sidechain, multiband or studio-grade digital tricks, so players seeking surgical studio-style compression or extensive tone-shaping will need more complex pedals. Also, because the control set is compact, dialing very specific transient behavior requires compromise - you either preserve more attack or go for more sustain, but there isn’t a separate Blend control to do both at once. Finally, while the build is solid, the slightly larger footprint means it won’t be the smallest option for ultra-tight pedalboards.

Final Verdict

The Harley Benton Custom Line CS-5 Compressor is a no-nonsense stompbox that delivers reliable compression and usable sustain at a very attractive price point - it’s ideal for players who want a compact, stage-proof compressor that’s quick to dial in. I’d recommend it to gigging guitarists who need a straightforward tool to tighten cleans and add sustain, and to beginners who want to learn how a compressor shapes dynamics without getting overwhelmed. If you need feature-heavy studio compression or a transparent blend knob, look elsewhere, but for value and dependable performance the CS-5 impressed me.
