Tout le monde connait la Reverb Unit de Fender. J'en avais fait ma version am\u00e9lior\u00e9e ici<\/a>.\u00a0 Mais....<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0 Au tout d\u00e9but des ann\u00e9es 60, les effets \u00e9taient basiques : reverb et temolo. La surf music s'est empar\u00e9e de cette modernit\u00e9, gr\u00e2ce notamment \u00e0 ce nouveau tremolo pr\u00e9sent dans les amplis Brownface et Blond de 1960 \u00e0 1963.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

\u00a0\u00a0\u00a0\u00a0 In the early 60s', the effects were basic, but so fancy ! Reverb and Tremolo. The Surf Music jumped into this modernity, especially with this new Tremolo developed by Fender in their Brown and Blond amps from 1960 to 1963.<\/span><\/em><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

\u00a0\u00a0\u00a0\u00a0 Pour beaucoup,\u00a0 ce trem est le meilleur jamais con\u00e7u. On l'a appel\u00e9 le Harmonic Tremolo.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0 Son secret ? S\u00e9parer graves et aigus et leur appliquer une modulation invers\u00e9e. Un peu comme les rotors d'une Leslie qui tournent dans des sens oppos\u00e9s. Le r\u00e9sultat est un tremolo beaucoup plus complexe et hyper organique. Au passage, il est un peu similaire \u00e0 celui utilis\u00e9 par Vox dans les AC30 et AC15, et issu des circuits d'orgues Wurlitzer.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

For many, it was the best trem ever made. It was called the Harmonic Tremolo.<\/span><\/em><\/p>\n

 <\/p>\n

\u00a0\u00a0\u00a0\u00a0 Its secret? Split the bass and treble and apply reverse modulation to them. A bit like the rotors of a Leslie that turn in opposite directions. The result is a much more complex and hyper-organic tremolo. It's a bit similar to the one used by Vox in the AC30 and AC15, and derived from Wurlitzer organ circuits.<\/span><\/em><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

\u00a0\u00a0\u00a0\u00a0 J'ai ici recr\u00e9\u00e9 la version \u00e0 5 triodes (il existe aussi un mod\u00e8le \u00e0 4 triodes, plus commun mais moins int\u00e9ressant), toujours en am\u00e9liorant le plus possible le circuit et sans rien laisser au hasard. <\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0 Tube 6K6GT NOS (pas d'EL84 ou de 6V6 qui sonnent diff\u00e9remment), du vrai<\/em> point \u00e0 point, un tank de reverb s\u00e9lectionn\u00e9, et une fa\u00e7ade en fr\u00eane olivier. Le r\u00e9sultat est organique \u00e0 souhait et absolument envoutant.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

\u00a0\u00a0\u00a0\u00a0 I've recreated the 5-triodes version (there's also a 4-triodes model, which is more common but less interesting), always improving the circuit as much as possible and leaving nothing to chance.<\/span><\/em><\/p>\n

\u00a0\u00a0\u00a0\u00a0 NOS 6K6GT tube (no EL84 or 6V6, which sound different), true point-to-point, a selected reverb tank, and an olive ash front. The result is beautifully organic and absolutely haunting.<\/span><\/em><\/p>\n
