The Crush Bass 25 nails that classic Orange warmth in a compact practice amp that punches well above its weight. It’s a 25-watt all-analogue combo with an 8″ speaker, a 3-band EQ built around a sweepable parametric mid control, a chromatic tuner, and a CabSim headphone output. For a practice amp that fits under a desk, it’s got a surprising amount going on.
What I appreciate most is the parametric mid. Most practice combos give you a fixed mid control and call it a day. Here you can sweep the frequency centre across a wide range, which means the same amp can sound scooped and punchy for rock, or thick and present for R&B and jazz. The fully analogue signal path keeps things warm and musical at any volume, and the ported rear-loaded cabinet squeezes noticeably more low-end out of that 8″ driver than the size would suggest.
Reading the panel left to right: Volume is the large knob on the left, followed by Treble, Middle, Freq and Bass. The Pad switch sits at the far right. Volume sets overall output. Treble, Middle and Bass are your standard EQ band controls with boost and cut. Freq is the parametric centre frequency sweep: it sets the frequency point that the Middle knob acts on, letting you focus the mid boost or cut wherever it’s most useful. The Pad switch engages a -6 dB input pad, which tames hot active bass signals before they hit the preamp.
In the demo above I’ve set up sweeps for Treble, Middle, Freq and Bass so you can hear what each one does to the same riff. The Pad sweep lets you compare the signal level with and without the pad engaged.
The three main presets map the amp’s tonal range. Neutral (all EQ at 5) shows the natural character of the amp: warm and rounded, with the low end doing most of the work. Pokey pushes the Middle to 8 with the Freq at 7, pulling up a forward, attack-focused mid presence that cuts through a mix. Rock Sub pulls the Middle back to 3 and the Freq to 3, with the Bass lifted to 7 for a scooped, chest-thumping voice. Through all three the all-analogue path keeps the sound musical rather than sterile, which is not a given in solid-state practice amps.
The headphone output with CabSim circuitry is the real standout for home use. Sounded really good straight out of the Phones jack, no extra DI or interface needed.
The Crush Bass 50 is the obvious sibling. The 50 runs twice the wattage through a 12″ speaker, giving it more headroom and low-end extension for smaller gigs. It also adds Blend and Gain controls for overdrive tones, letting you mix a driven signal in with your clean fundamental for those thick “bi-amped” sounds. The 50 also includes a buffered effects loop. The 25 has none of that: no overdrive circuit, no effects loop, a smaller speaker and lower output.
What the 25 has going for it is size and simplicity. At 8.3 kg it’s genuinely grab-and-go, and the control set stays focused on shaping your clean tone. If your playing is clean and your rehearsals happen at home or in a small room, the 25 covers the same core Orange character without the extra bulk. If you want to push into driven territory or need enough volume for a drummer, the 50 is the one.
Bass players who practice at home and want a compact amp that sounds like a proper Orange rig. The CabSim headphone output makes late-night silent practice genuinely enjoyable rather than a compromise. The parametric mid sweep is flexible enough for most styles, from fingerstyle jazz to picked rock. The aux input lets you run a phone or laptop in for practice-along sessions.
The honest caveats: 25 watts through an 8″ speaker is not a gigging amp. It’ll hold up in a quiet rehearsal space, but it won’t compete with a loud drummer. There’s also no overdrive circuit here, so if driven bass tones are part of your sound, the Crush Bass 50 is the better fit.
