Description

Ibanez produced the TS808DX Tube Screamer Overdrive Pro Deluxe as an expanded iteration of the long-established TS808 Tube Screamer, positioning it as a dual-function unit combining the original overdrive circuit with an integrated boost stage in a single enclosure.

The overdrive section retained the JRC4558D IC that defined the TS808's characteristic soft clipping behaviour, governed by Overdrive, Tone, and Level controls. The added boost circuit offered up to 20 dB of gain and was controlled by its own dedicated switch, with a toggle on the unit allowing the boost to be placed either pre- or post-overdrive. Each section operated through an independent true bypass switch, permitting the overdrive and booster to function separately or in combination. A rear-panel voltage switch provided the option of 9-volt or 18-volt operation, with power draw of 43 mA at 9 V and 114 mA at 18 V. The unit accepted a single 9-volt battery (006P) or an external DC 9 V centre-negative AC adapter.

Owners sourcing a replacement AC adapter should confirm the centre-negative DC 9 V specification before use; a qualified guitar technician or electronics repair professional can assist with internal service or fault diagnosis.

Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.

Put yours on the record.

The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.

What do you know about this one?

Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
