Je vends un ampli AMPEG MODEL 830 BASSAMP de 1958 dans un excellent état.
C'est le grand frère du portaflex qui est sorti 2 ans avant.
Le son est très proche des premiers B15N, ça crunch à partir de 5, idéal pour le studio, un peu léger pour une batterie rock mais ok en jazette. Beaucoup de guitaristes l'utilisent aussi. Equipé en tubes de puissance Mullard EL37 et préamp Sylvavia ! HP changé récemment par un Eminence Kappa Pro 15 pouces 8ohms (180€), sinon tout est d'origine. Le grill cloth semble fait par un amateur mais c'est bien celui d'origine ! Il y a encore l'adresse de la société Ampeg qui est celle de 1958.
Construction du cabinet haut de gamme en bois massif ! Ampli révisé récemment. Nouveau cordon d'alimentation (110v). Transfo 110-220 dispo pour 30 €. Essai possible à mon studio à Montreuil métro Robespierre.
Il est en très bel état pour un ampli de cet age. photos sur demande.

Historique
The Bassamp was the first amp produced by Ampeg beginning in 1948. It was originally designed to provide amplification for upright string basses that used Ampeg's original string bass pickup known as the "Ampeg," hence the origin of the company's name. The Bassamp underwent various changes before being discontinued around 1960. Each modification was denoted by a corresponding change in model number with the first being the pre-Ampeg Michael-Hull Model 770 (1946) and the last being the Model 835 (1958). Until the late 1960s, Ampeg's bass amplifiers were better suited for bass compared to those made by other manufacturers whose bass amps were generally better for guitar. The Bassamp was discontinued by 1961 due to the introduction of the B-15N Portaflex. The amp shown here has a vinyl covering color that was short lived. This baby blue "random flair" vinyl appeared in mid-1958. According to Jess Oliver, former Vice President of Ampeg, this covering was transitional between the earlier gray and/or tan bookbinding coverings, and the navy "random flair" vinyl that was used from late 1958 to mid-1963. The Bassamp series, like the Guitaramp and Accordiamps series, used a split chassis design which separated the preamp section from the power amp section of the circuit.

J'utilise la rubrique du Portaflex car celle du Bassamp 50's n'existe pas sur Audio Fanzine. Merci de votre compréhension.
