Crazy Tube Circuits announced two all-analog pedals in December 2020: the Constellation CV7003 fuzz and the Memphis vibrato¹²³. Guitar Pedal X dated its report December 11, 2020²; Gearnews dated its report December 13, 2020³.

The Constellation CV7003 is a hand-built fuzz pedal built around hand-selected NOS germanium CV7003 transistors that Gearnews describes as military spec and made in 1968 by Texas Instruments in the UK¹³. Guitar Pedal X describes the CV7003 as equivalent to the OC44 and as the same sort of transistor used in the original 1966 Dallas RangeMaster Treble Booster². A large dial selects the fuzz voicing, alongside volume and gain knobs³. The six modes, as listed by Guitar Pedal X, are FF (Fuzz Face), VTB (Vox Tone Bender), 3/2 (Tone Bender MKI.V), 2 (Tone Bender MKII), RM (RangeMaster) and RMFF (RangeMaster into Fuzz Face)². Crazy Tube Circuits describes RMFF as "A future classic combination"³. The run is limited to 200 units worldwide¹³. Gearnews gives a US list price of USD 299 and says the pedal ships in a wooden box³.

The Memphis is a pitch-shifting vibrato based on the Magnatone amps of 1970s California, and Crazy Tube Circuits positions it as the "small brother" of its Killer V pedal, without the drive section¹. It uses an analog LFO and a two-stage pitch shifting circuit, with a built-in preamp¹. Gearnews says the preamp offers up to 20dB of clean boost with a 1950s/1960s amp voicing³. Controls are Intensity, Speed and Volume, plus an All Dry/All Wet switch²³. Guitar Pedal X counts four controls against the Killer V's eight plus dual footswitches².

No US list price for the Memphis appears in the reports. Guitar Pedal X said the first batch of the Constellation sold out almost instantly².
