Electro-Harmonix Hot Tubes Nano Overdrive Pedal | No Limit Guitar Co, Idaho Falls
The Electro-Harmonix Hot Tubes Nano is a faithful recreation of one of EHX's most beloved vintage circuits — the original CMOS Hot Tubes overdrive from the 1970s — packed into a compact, rugged nano enclosure ready for any pedalboard. Incredibly responsive to playing dynamics, it rewards the nuances of your touch with organic, amp-like overdrive that cleans up beautifully when you back off your volume or lighten your pick attack. Whether you're looking for a touch-sensitive overdrive that reacts like a well-driven tube amp or a compact analog pedal that adds grit without killing your tone, the Hot Tubes Nano delivers the goods.
Product Overview
The Hot Tubes Nano's CMOS-based analog circuit is the heart of what makes this pedal feel different from standard clipping overdrive designs. CMOS technology produces an overdrive character that responds dynamically to how hard you play — dig in and the pedal pushes back with aggression and harmonic richness; ease up on your pick attack or roll back your guitar's volume knob and it cleans up with the natural, responsive sweep you'd expect from a well-set tube amplifier. This level of touch sensitivity gives the Hot Tubes Nano a living, breathing quality that static, hard-clipping overdrives simply can't replicate.
Three controls — Volume, Overdrive, and Tone — keep the interface simple and intuitive, and a dedicated Tone On/Off bypass switch takes the tone circuit completely out of the signal path when you want an uncolored, direct overdrive without any EQ influence. This feature alone sets the Hot Tubes Nano apart from most compact overdrive pedals in its price range, giving players a meaningful choice between a shaped tone and a pure, unfiltered signal. True bypass switching ensures your guitar's unaffected tone passes through cleanly when the pedal is off, with no signal degradation.
The die-cast chassis is compact enough to fit comfortably on any pedalboard — just 2.2" wide, 4.3" deep, and 2" tall — and weighs in at a negligible 0.55 lbs. A 9V battery is included for immediate use, and the pedal can also be powered via an optional AC adapter for permanent pedalboard installation.
Ideal For
- Electric guitarists seeking a touch-sensitive, amp-like overdrive that responds organically to playing dynamics and volume control adjustments
- Blues, rock, and classic rock players who want a vintage 1970s CMOS overdrive character in a modern, road-worthy enclosure
- Pedalboard builders looking for a compact, true bypass overdrive that won't color the signal when disengaged
- Players who prefer a no-frills, three-knob overdrive with the added flexibility of a tone circuit bypass switch
- Guitarists in Idaho Falls building their first pedalboard or adding a proven vintage-voiced overdrive to an existing rig
Key Features
1970s CMOS Circuit Recreation The Hot Tubes Nano faithfully replicates the analog CMOS circuit of the original 1970s Hot Tubes pedal — a design that produces overdrive with a dynamic, harmonically rich character distinctly different from standard diode-clipping overdrives, and far more responsive to the nuances of individual playing technique.
Touch-Sensitive Playing Dynamics The CMOS circuit responds directly to how hard you play — pushing the circuit harder as your attack increases and cleaning up smoothly as you back off — giving the overdrive a natural, amp-like responsiveness that rewards expressive playing and makes your volume knob a genuine tone-shaping tool.
Tone Circuit Bypass Switch A dedicated Tone On/Off switch removes the tone circuit entirely from the signal path, delivering a completely uncolored overdrive signal when engaged — a practical and sonically meaningful option for players who want pure CMOS grit without any EQ shaping.
True Bypass Switching True bypass design passes your guitar's signal directly through the pedal with no buffering or coloration when the effect is disengaged, preserving the integrity of your tone across even long signal chains.
Compact Die-Cast Chassis The rugged die-cast enclosure measures just 2.2" × 4.3" × 2" and weighs 0.55 lbs. — small enough to fit on the tightest pedalboard without sacrificing the build quality needed to withstand regular gigging and touring use.
