The Deluxe Nanoverb Amp 64' is a very unique product that combines a full-fledged vacuum tube preamp with digital reverb. Its construction is more like an amplifier than an effects pedal. The pre-main circuit reproduces the VIBRATO channel of the Deluxe Reverb, a standard among studio professionals and musicians, with particular attention paid to the sound of the 1964 vintage model. First of all, you will be surprised by the sound pressure, which is unimaginable from the size of the main unit. You will clearly feel the difference from digital simulation and ideas for the right tool for the right place will come to mind. The effects, curves, and constants of the two EQs are designed based on the real thing, and the passive filters are also the same. The coupling capacitors and tone filters use film capacitors used in amplifier manufacturing. The resistors are made by DALE and carbon composite. It incorporates many circuit techniques, but most of it is designed with an analog focus. The preamp circuit is mainly made up of back components, and the design is as close to hand-wired as possible. The vacuum tube is a JJ 12AX7, and a boost voltage of about 280V is applied to the plate resistor. The function configuration is as follows: -Vacuum tube pre-main -Digital reverb -Convenient master VOL -Stereo emulated output (Line output or headphones) 3.5mm jack *Via analog-designed cabinet simulator. (1x10 open-back style analog cabinet) -AUX input 3.5mm jack -The internal board has a switch similar to inserting a VIBRATO channel and inputs 1 and 2. <Factory default setting: Input 1 (HIGH)> In studio use, connecting it to the input of a JC120 amplifier will give you the effect of replacing a tube amplifier. Also, by connecting it to the return of various amplifiers, this unit can function as an amplifier control. Even if you have to use poorly maintained equipment on site, you can play with your usual settings. *When connecting to a power amplifier, the signal is directly connected via through bypass, so be sure to keep the red LED lit when using. Otherwise, the speaker may be damaged. Another way to use it is as a reverb pedal with two EQs. Many amplifiers have built-in reverb functions that do not operate independently, but are driven by elements such as vacuum tubes or replaced op amps and incorporate a MIX circuit. This unit can be used as if you were controlling the reverb of a tube-driven amplifier with your feet. The LINE output supports stereo output, and can be converted from 3.5mm using an external conversion adapter (sold separately) to adapt to a variety of devices. You can also bypass the CAB SIM and output the original sound using a regular OUTPUT such as an audio interface or IR loader. This is an extremely useful item, perfect for those who find it inconvenient to carry around a real amp, or who feel that digital simulator software is not enough. It looks cute, but its essence is a solid, solid design. It also doesn't fit into categories such as professional, intermediate, or beginner. The key is whether the tone of this preamp suits your tendencies and playing style. It has a straightforward clean amp tone with no quirks. This is a product that you should definitely try. 〈specifications〉 ・Size: 62 x 118 x 39 mm ・12VDC adapter only（500mA～） ・JJ 12AX7 Valve ・True bypass ・Please note that product specifications and parts may change without notice.
