The main features of Valve Crystal Custom Deluxe50 are as follows. ・Tube main circuit (Green Ch) (Passive 3EQ, 4 type tone selection switch) ・Tube booster (ODS_Red Ch) ・REVERB (Digital Spring Style) ・Active FX LOOP (send, return) ・Emulate line out/headphones ・50W power amplifier (class D) 4-8Ω All you need is a guitar and a cabinet. The main circuit has a circuit configuration inspired by the DUMBLE ODS AMP, and applies a high voltage of over 250V to drive the vacuum tube. This corresponds to the voltage applied to the plate resistor of the actual machine. The main configuration is a vacuum tube integrated circuit, with a passive 3-band EQ and 4 types of switches to refine the tone. (clean) In ODS mode, the signal passes through the subsequent vacuum tube boost circuit. Although it is a drive channel, it can be set intuitively if you think of it as a booster for the main settings that control OD gain and OD level. (This is the general operation of a Dumble type amplifier) DUMBLE's dazzling high range is made up of integrated components and a distinctive EQ circuit, but we interpret that much of its sound pressure and push is brought about by the high-gain power amplifier section. When designing the power amplifier stage, we made sure that it could be driven by a regular 12V DC power supply and that it could generate enough sound pressure to be used on a small stage. Adopts a class D power amplifier IC to achieve 50W output while saving power. The unity gain of the IC is increased and some distortion is added to the power amplifier section. This is because actual Fender amplifiers usually use a 12AT7 as a phase inverter, but Mr. Dumble's modification uses a 12AX7. The power amplifier section is designed based on that image and interpretation. REVERB uses digital elements to recreate the deep sway of a spring breeze. A natural REVERB equipped with a parallel MIX circuit that blends smoothly into the original sound. Additionally, it is equipped with an FX loop (SEND & RETURN) that allows you to extract the pre-main sound from SEND and connect it to other power amplifiers (return plugs, etc.). Also, by inserting your favorite preamp into the RETURN of this unit, you can use it as a 50W power amplifier just like a normal AMP return. An additional feature is an emulated line output, which can also be used as a headphone output. This is a line output via an open back cabinet simulator. (Genuine pre-main output can be taken out from SEND) When using LINE, there is no need to connect cabinets or dummy loads, so the work space can be minimized. The product specifications aim for the highest quality structure and finish as a DUMBLE floor pedal. Please give it a try. ～Various functions～ Clean section (green LED mode) ・Gain, treble, middle, bass, master ・VOICE switch ・BRIGHT switch ・MID switch ・DEEP switch ODS section (red LED mode) ・OD gain ・OD level reverb section ・Reverb mix -Foot switch- ・Right foot switch Toggle between Clean (Green LED) and ODS Boost (Red LED). ・Left foot switch Reverb ON-OFF (blue LED when ON, off when OFF) -Input/output- ・DC jack *12V1A center negative drive ·input ・SEND (pre-main out) ・RETURN (power amp in) ・LOOP +4db/-10db selector switch ・LINE OUT & HEADPHONE (Emulate Out) ・Power amplifier out (4Ω, 8Ω) *If you are using LINE, there is no problem even if you do not connect a speaker. *When connecting speakers, be sure to set MASTER to 0. *Do not connect anything other than speakers to SPEAKER OUT. -size- W170mm D124mm H55mm Weight 740g
